Radio Receivers If the intermediate frequency is very high (indicate false statement) Image frequency rejection is very good The selectivity will be poor The local oscillator need not be extremely stable Tracking will be improved Image frequency rejection is very good The selectivity will be poor The local oscillator need not be extremely stable Tracking will be improved 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, full-carrier ISB Single-sideband, reduced-carrier Single-sideband, suppressed-carrier Single-sideband, full-carrier ISB Single-sideband, reduced-carrier ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The controlled oscillator synthesizer is sometimes preferred over the direct one because Its frequency stability is better It is relatively free of spurious frequency It does not require crystal oscillator It is a simpler piece of equipment Its frequency stability is better It is relatively free of spurious frequency It does not require crystal oscillator It is a simpler piece of equipment ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers The local oscillator of a broadcast receiver is tuned to a frequency higher than the incoming frequency To permit easier tracking Because otherwise an intermediate frequency could not be produced To help the image frequency rejection To allow adequate frequency coverage without switching To permit easier tracking Because otherwise an intermediate frequency could not be produced To help the image frequency rejection To allow adequate frequency coverage without switching ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers If a FET is used as the first AF amplifier in a transistor receiver, this will have the effect of Improving the effectiveness of the AGC Reducing the effect of noise at low modulation depths Reducing the effect of negative-peak clipping Improving the selectivity of the receiver Improving the effectiveness of the AGC Reducing the effect of noise at low modulation depths Reducing the effect of negative-peak clipping Improving the selectivity of the receiver ANSWER DOWNLOAD EXAMIANS APP
Radio Receivers In a ratio detector the output is twice that obtainable from a similar phase discriminator stabilization against signal strength variations is provided the linearity is worse than in phase discriminator the circuit is the same as in a discriminator, except that the diodes are reversed the output is twice that obtainable from a similar phase discriminator stabilization against signal strength variations is provided the linearity is worse than in phase discriminator the circuit is the same as in a discriminator, except that the diodes are reversed ANSWER DOWNLOAD EXAMIANS APP
