This file type includes high resolution graphics and schematics when applicable. Generating a high-frequency magnetic field can be quite a challenge due to an assortment of technical issues. At high ...

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, ...

The FM modulator circuit (frequency modulation) is built with a Motorola MC1648P oscillator. Two varactors, Motorola MV-209 are used to frequency modulate the oscillator. The 5000 Ω potentiometer is ...

Many systems divide a crystal frequency by an integer number to generate clock signals. Unfortunately, the integer divisor limits the available set of output frequencies. Applications such as ...
