In contrast to digital circuits, analog circuits use signals whose voltage levels are not constrained to two distinct levels, but instead can assume any value between Vdd and GND. Many input devices, particularly those using electronic sensors (e.g., microphones, cameras, thermometers, pressure sensors, motion and proximity detectors, etc.) produce analog voltages at their outputs. In modern electronic devices, it is likely that such signals will be converted to digital signals before they are used within the device. For example, a digital voice-memo recording device uses an analog microphone circuit to convert sound pressure waves into voltage waves on an internal circuit node. A special circuit called an analog-to-digital converter, or ADC, converts that analog voltage to a binary number that can be represented as a bus in a digital circuit. An ADC functions by taking samples of the input analog signal, measuring the magnitude of the input voltage signal (usually with reference to GND), and assigning a binary number to the measured magnitude. Once an analog signal has been converted to a binary number, a bus can carry that digital information around a circuit. In a similar manner, digital signals can be reconstituted into analog signals using a digital-to-analog converter. Thus, a binary number that represents a sample of an audio waveform can be converted to an analog signal that can, for example, drive a speaker.

A PCB Layout is the resulting design from taking a schematic with specific components and determining how they will physically be laid out on a printed circuit board. To produce a PCB Layout, you must know the connections of components, component sizes (footprints), and a myriad of other properties (such as current, frequencies, emissions, reflections, high voltage gaps, safety considerations, manufacturing tolerances, etc.).

This is a particularly insidious problem that can easily ruin a good project. In very general terms it is formed whenever there are multiple signal ground paths to the same termination. I can be internal or external to the piece of equipment. The most frequent result is a hum that either will not go away or happens only when something is connected to the piece of equipment. I need now to provide a few brief words about hum. If the hum is at the same frequency as the AC mains (either 50 or 60 Hz typically) then it is likely from interconnections external to the equipment or poor shielding internal to the equipment. If the hum is at twice the mains frequency then it nearly always because of inadequate power supply filtering. Ground loops are usually at the mains frequency. So if you encounter one, then you must search for the alternate ground paths that relate to the signal chain. If it external (occurs only when the equipment is attached to an external item), then check for things like phonograph grounding at the phonograph end. As an example I have seen is when one terminal of a cartridge connected to the ground in the tone arm (OK and fairly common) and a separate ground from the same tone arm (not OK) is provided for connection to the amplifier chassis ground (this is not to be confused to the situation when there is a separate ground wire from the phonograph chassis that has no connection to the ground in the cartridge). Since both the signal ground and tone arm ground are connected at the phonograph they will form a ground loop (between the shields and ground wire) when connected to the amplifier. The solution in such cases is to separate the grounds at the phonograph. An internal example was mentioned earlier when both ends of internal shielded cables are joined in two different places (at the input jacks and volume control). The irony of the situation and part of the insidious nature of ground loops is that they can on occasion be benign and not cause hum. They can later show up when a new piece of equipment is attached to the system. In all cases however, they have the same fundamental cause, alternate paths for the signal return.

Many different types of components and devices can be found in modern circuits, including resistors, capacitors, and inductors, semiconductor devices like diodes, transistors, and integrated circuits, transducers like microphones, light sensors and motions sensors, actuators like motors and solenoids, and various other devices like heating and lighting elements. Devices in a circuit are connected to one another by means of electrical conductors, or wires. These wires can move electric currents between various points in a circuit. Once a wire connects two or more devices, the wire and all attached device connectors are said to form a single circuit node or net. Any electrical activity on a given net is communicated to all devices attached to the net. Certain nets provide electric power to devices, and other nets carry information between devices. Nets that carry information are called signals, and signals transport information encoded as voltage levels around a circuit. Signal nets typically use smaller conductors, and transport very small currents. Nets that carry power are called supply rails (or just supplies) and supply rails transport electric power around a circuit. Power nets typically use much larger conductors that signal nets, because they must transport larger currents.

By Sasha Sara. Diagram. Published at Friday, October 20th 2017, 16:52:54 PM. A digital circuit is constructed of a power supply, devices, and conduction nets. Some nets provide circuit inputs from the “outside world”; in a schematic, these input nets are generally shown entering the left side of component and/or the overall circuit. Other nets present circuit outputs to the outside world; these nets are generally shown exiting the schematic on the right. In the sample schematic below, circuit components are shown as arbitrary shapes, nets are shown as lines, and inputs and outputs are denoted by connector symbols.

Most of the electrical symbols can be changed in their appearance, styles and colors according to users requirements. Electrical symbols are used to represent various electrical and electronic devices in a schematic diagram of an electrical or electronic circuit.

The load current specification for an IC regulator will be defined as either a single value or a value that is dependent on input-output voltage differential (this is detailed in the following section on protection circuits).

By Lydie Honorine. Circuit. Published at Friday, October 13th 2017, 13:12:13 PM. The real part and imaginary part of impedance are interpreted as a resistive part that dissipates energy and a reactive part that stores energy. Resistors can only dissipate energy and therefore their impedances have only a real part. Capacitors and inductors can only store energy and therefore their impedances have only an imaginary part. When resistors, capacitors, and inductors are combined, the overall impedance may have both real and imaginary parts. It is important to note that the definition of impedance preserves the definition of resistance.

The variable resistor remains a two-terminal device, so the arrow is just laid diagonally across the middle. A potentiometer is a three-terminal device, so the arrow becomes the third terminal (the wiper).

## Measurement Of CurrentMeasurement Of Current

By Valentine Sybille. Circuit. Published at Tuesday, October 10th 2017, 11:14:52 AM. An often used and sometimes confusing term in electronic circuits is the word ground. The ground is a circuit node to which all voltages in a circuit are referenced. In a constant voltage supply circuit, one terminal from each voltage supply is typically connected to ground, or is grounded. For example, the negative terminal of a positive power supply is usually connected to ground so that any current drawn out of the positive terminal can be put back into the negative terminal via ground.
