Radio Receivers Indicate the false statement. The superheterodyne receiver replaced the TRF receiver because the latter suffered from Instability Inadequate selectivity at high frequencies Gain variation over the frequency coverage range Insufficient gain and sensitivity Instability Inadequate selectivity at high frequencies Gain variation over the frequency coverage range Insufficient gain and sensitivity ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because It does not require crystal oscillator It is relatively free of spurious frequency Its frequency stability is better It is a simpler piece of equipment It does not require crystal oscillator It is relatively free of spurious frequency Its frequency stability is better It is a simpler piece of equipment ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers An AM receiver uses a diode detector for demodulation. This enables it satisfactorily to receive Single-sideband, suppressed-carrier Single-sideband, reduced-carrier Single-sideband, full-carrier ISB Single-sideband, suppressed-carrier Single-sideband, reduced-carrier Single-sideband, full-carrier ISB ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers A low ratio of the ac to the dc load impedance of a diode detector results in Poor AGC operation Negative-peak clipping Poor AF response Diagonal clipping Poor AGC operation Negative-peak clipping Poor AF response Diagonal clipping ANSWER DOWNLOAD EXAMIANS APP
