Q. Explain Current-to-Current Amplifier ?
The circuit given in Figure is to amplify a current fed to the input of the op amp. Applying KCL at Y,
i1 + iS = io
Since i1 = - vY /R1, Equation becomes
iS - vYR1 = io
Because X is a virtual ground, vY =-iSRf . Hence Equation becomes
The current gain is then given by
Single Phase Full Wave Controlled rectifier The single phase half wave controlled rectifier produce only one pulse of load current during one cycle of supply voltage
Q. Digital demodulator processes? The functions of the receiver in Figure are the inverse of those in the transmitter. At the receiving end of a digital communication system, t
