AM Detector Receivers One of the basic RF receiver architectures for detecting a modulated signal is the amplitude modulation (AM) detector receiver (see Fig. 8-2). The name comes from the fact that ...

The standard hardware requirements for sample-and-hold and peak detector circuits apply to D1, C1, and A2. C1 must be a high-quality capacitor, D1 must be a low-leakage diode, ...
