Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors ...

For a more analog MOSFET application, consider this simple AM modulator. Figure 4 MOSFET amplitude modulator. The circuit consists of an N-channel MOSFET, two resistors, and a Schottky diode. The ...

Oct 17, 2007 12:00 AM. ... The nanotech device is a demodulator, a simple circuit that decodes radio waves and turns them into audio signals. By hooking the decoder up to two metal wires, ...

The second was to show a live real-time end-to-end chain consisting of High Definition (HD) source material, a DVB-T2 modulator, a DVB-T2 demodulator and an MPEG-4 video decoder showing pictures ...

He’s broken down the modulation and demodulation circuits into their basic op-amp stages with examples of what the signal should look like on a scope after each stage. That’s the beauty here.
