Question
The receiver portion of a radio system is shown in Figure 1 below, in the green shaded box. Briefly describe the functions of each component in the receiver portion of a radio system in terms of how each component transforms the receiving signal from the antenna to the input of the A/D converter for further processing and storage.
Power Supply & Management Video Amp LO Audio Diplexer storage Antenna & RF Frontend Baseband Backend Propagation Figure 1. The top-level block diagram of a radio systemExplanation / Answer
Power supply and management is used to provide power to onboard equipment.
Antenna is used to transmit and receive signal
Duplexer transfer signal to transmit ckt
Bandpass filter allows frequency which is in band and reject other.
Low noise amplier is used to amplify low signal received from antenna
PA is power amplifier it increase the power
Local oscillator are used to change the frequency coming from antenna along with mixer
Mixer is used to add it subtract frequency
Low pass filter allows only low frequency signal and reject high frequency signal
Amplifier is used to increase power of signal
A/d d/a are used to convet analog to digital and vise versa
Audio input /output is used for audio signalvi.e low frequency signal
Storage to store data
Vedio used for vedio signal I.e high frequency signal
