1.	In semiconductor physics, what is meant by:(i) rectifier (ii) an amplifier (iii) an oscillator
Answer» (i) Rectifier: It is a device which converts alternating current into direct current. (ii) Amplifier : An amplifier is a device which increases the energy of a weak signal by supplying energy from an external source. An amplifier increases the amplitude of a input signal. (iii) Oscillator: An oscillator is a device which produces electrical oscillations of adjustable frequency and constant amplitude. An oscillator is basically an amplifier. A part of the output energy is fed back into the L-C circuit to produce sustained oscillations. .
