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 ...

3.5 Results: Demodulation of two-level amplitude-modulated data. We used data obtained from an actual optical system to test the accuracy of our demodulation technique.

• 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. • ...

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 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 ...

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 ...
