Radio Receivers Indicate which of the following circuits could not demodulate SSB: Product modulator Phase discriminator BFO Balance modulator Product modulator Phase discriminator BFO Balance modulator ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The local oscillator of a broadcast receiver is tuned to a frequency higher than the incoming frequency Because otherwise an intermediate frequency could not be produced To allow adequate frequency coverage without switching To help the image frequency rejection To permit easier tracking Because otherwise an intermediate frequency could not be produced To allow adequate frequency coverage without switching To help the image frequency rejection To permit easier tracking ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers If the intermediate frequency is very high (indicate false statement) The selectivity will be poor Tracking will be improved Image frequency rejection is very good The local oscillator need not be extremely stable The selectivity will be poor Tracking will be improved Image frequency rejection is very good The local oscillator need not be extremely stable ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers Indicate the false statement. The superheterodyne receiver replaced the TRF receiver because the latter suffered from Gain variation over the frequency coverage range Insufficient gain and sensitivity Inadequate selectivity at high frequencies Instability Gain variation over the frequency coverage range Insufficient gain and sensitivity Inadequate selectivity at high frequencies Instability ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers An AM receiver uses a diode detector for demodulation. This enables it satisfactorily to receive Single-sideband, full-carrier ISB Single-sideband, reduced-carrier Single-sideband, suppressed-carrier Single-sideband, full-carrier ISB Single-sideband, reduced-carrier Single-sideband, suppressed-carrier ANSWER DOWNLOAD EXAMIANS APP
