Radio tuning and detection circuit
Source: InternetPublisher:MartinFowler Keywords: Radio detector circuit demodulation multimeter Updated: 2020/12/08
Shown is the radio demodulation and detection circuit . The AM intermediate frequency signal is detected by the diode Dr after two stages of intermediate frequency amplification.
The audio signal is detected from the intermediate frequency carrier and then sent to the power amplification circuit of the subsequent stage. The demodulated and detected waveforms can be debugged
and tested with a multimeter and oscilloscope.
