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, ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

Pulse Width Modulation (PWM) is a basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED ...

In the past few years, the pitch on digital control of switching regulators has been rising steadily. In a typical analog implementation, a pulse-width-modulated (PWM) switching regulator is built ...

This helps provide overspeed protection by sending signals that warn the logic solver to alarm or shut down the monitored device for plant, process and personnel safety. The transmitter has been ...
