Choosing IF Frequencies 190MHz and 70MHz were chosen to be the 1st (f1_ IF) and the 2 nd (f2 _ IF) IF frequencies respectively. The corresponding 1st (f1_ LO) and 2 nd (f2 _ LO) local oscillation (LO) Web9-1 FM Superheterodyne Receivers FM receivers use the superheterodyne principle, as shown in Figure 9-1. Recall that ... • Describe the features of noise-suppressing circuits in an FM receiver. • Draw a block diagram of a frequency-synthesized FM receiver. • Trace the signal flow through FM stereo and SCA decoder circuits.
The diagram at right shows the block diagram of a typical single-conversion superheterodyne receiver. The diagram has blocks that are common to superheterodyne receivers, with only the RF amplifier being optional. The antenna collects the radio signal. The tuned RF stage with optional RF amplifier provides some initial selectivity; it is necessary to suppress the imag… WebSep 13, 2024 · The IF amplifier fulfills the gain and bandwidth requirements of the receiver. Block Diagram of Superheterodyne Radio Receiver. The detector received the amplified IF signal to detect the information signal component from 455 kHz IF, to reproduce the original information data, which is generally in the form of the audio signal.
