Q. What is a clamper? Differentiate between a clamper and clipper.
Clamping network shifts (clamps) a signal to a different dc level, i.e. it introduces a dc level to an ac signal. Hence the clamping network is also known as dc restorer. These circuits find application in television receivers to restore the dc reference signal to the video signal. During the positive half cycle, the diode conducts, i.e. it acts like a short circuit. The capacitor charges to V volts. During this interval, the output which is taken across the short circuit will be Vo = 0 V. During the negative half cycle, the diode is open.
The difference between clipping and clamping circuits is that while the clipper clips off an unwanted portion of the input waveform, the clamper simply clamps the maximum positive or negative peak to a desired dc level.
Flicker noise: I’d like to plot the graph of the flicker noise found in the data sheet for the amplifier (will be provided later) and also generate the equation for that graph sho
Use the offset diode model with a threshold voltage of 0.6 V to determine the value of v 1 for which the diode D will first conduct in the circuit of Figure(a).
Define Smoothing the Output? The output of a DAC is stepped, such as the analog waveforms which were sampled and held. This stepped, or staircase effect is a distortion, and it

applications of dynamically induced emf
A three-phase, wye-connected, 2300-V, 60-Hz, round-rotor synchronous motor has a syn- chronous reactance of 2 per phase and negligible armature resistance. (a) If the motor tak
Voltage is referred as Potential difference among two points. Potential means its force. I think so.voltage defination is 100% correct.
