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.
What are shift registers? Design a 8 bit shift register with features like PISO, SISO, SIPO and PIPO.

A signal comprises a bandwidth of 1kHz centred around 1kHz. A sine wave along with a frequency of 1250Hz is added to the signal. The bandwidth of the new signal is: 2250Hz
The signal m(t), whose frequency spectrum M(f ) is to be transmitted from one station to another. Let the signal be nor- malized, i.e., -1 ≤ m(t) ≤ 1. Find the bandwidth of the mod
