Discrete small-signal MOSFETs still find uses today, and this Design Idea presents two simple examples: an AND gate, and an amplitude modulator. Figure 1 shows a standard two-input AND gate along with ...

In pulse position modulation, the amplitude and width of the pulses are kept constant, while the position of each pulse with reference to position of reference pulse, is changed according to the ...

An interferometer modulator uses a beamsplitter to produce deflected and transmitted light beams onto mirrored surfaces of a piezoelectric crystal pair, one piezoelectric crystal being driven by a ...

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 ...

LASER COMPONENTS would like to introduce its phase modulator especially designed to operate in the 1000nm wavelength band. The NIR-MPX series use a proton exchanged based waveguide process that ...

In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air ...
