Figure 18 An amplitude modulated (high frequency) carrier signal and its low frequency sine wave modulating signal. In Figure 15 with a P Channel MOSFET, as the gate voltage approaches 0 volts, the ...

Doing this frees up the modulator output of Demodulator 2, which can be set to an arbitrary drive phase Φ X, at which the amplitude is maximum. The rate signal is now nulled by the modulator output of ...

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.

The resulting time-varying frequency, and thus varying phase of the vision carrier, is known as incidental phase modulation, ICPM. There are two basic types of circuits for demodulating ...

Conceptually the circuit there is simple, consisting of the ultrasonic receiver, followed by a transistor amplifier for the modulated wave, then a diode for demodulation, another transistor ...

• Providing an interferometric optical modulator which can be utilized as a digital photonic clock circuit, a pulse width/amplitude modulator circuit, and a bi-stable optical-memory cell circuit. • ...

The DVB-S2/S Demodulator IP core is a silicon-proven IP core extracted from Production chips. It contains tuner Rx gain control which makes PDM Demodulator a high performance (A)PSK output ... The DVB ...

This demodulator is suitable for the quadrature phase-shift keying (QPSK) modulator previously published by the same author, "Novel Low-Cost QPSK Modulator Needs No Adjustments" (electronic design ...
