The same effect causes a slight decrease in torque with speed in the constant torque region as well. Finally, there is a rounding of the torque curve at the corner speed because the drive gradually transitions from being a current source to being a voltage source. The drive limits current to the motor below the corner speed and thus is a current source. Above the corner speed, the motor’s inductive reactance limits the current and the drive becomes a voltage source as it applies all of the power supply voltage to the motor.

The class of operation for an amplifier is very important and is based on the amount of transistor bias required for operation as well as the amplitude required for the input signal. Amplifier classification takes into account the portion of the input signal in which the transistor conducts as well as determining both the efficiency and the amount of power that the switching transistor both consumes and dissipates in the form of wasted heat. Then we can make a comparison between the most common types of amplifier classifications in the following table.

For the longest time I could not remember which end of the diode was the anode and which was the cathode, I looked it up every time. I finally came up with this memory aid. The German word for cathode is Kathode. The big K kind of looks like a diode symbol.

If the ohmmeter reads a finite resistance, that means the diode is conducting a small current in the forward direction, and the red +++ lead from the meter is touching the anode. If the resistance reads O.L (for overload), the diode is not conducting current. That means the red +++ test lead is touching the cathode.

By Sasha Sara. Circuit. Published at Wednesday, December 27th 2017, 02:05:06 AM. For DC signals, the linearity of the system implies that H is independent of Vin. For dynamic signals, the transfer function cannot in general be described simply. However, if the input is a sinusoidal signal then the output must also be a sinusoidal signal with the same frequency but possibly a different amplitude and phase. In other words, a linear system can only modify the amplitude and phase of a sinusoidal input.
