Q. Discuss the disadvantages of an RC coupled amplifier?
RC coupled amplifiers have a few disadvantages. The resistors use dc power and so the amplifier has low efficiency. The capacitor tends to limit the low-Frequency response of the amplifier and the amplifying device itself limits the high-Frequency response.
Q. A commercial FMstation broadcasts a signal with 180-kHz bandwidth when |f(t)|max = 2 V. Find kFM for the modulator if the spectral extent of f (t) is 30 kHz, by using Carson's r
Q. Why the gain of the amplifier decreases if the CE is avoided? When the ce is connected in the circuit, ac signals get bypassed through it to the ground. In the absence of Ce
