FM modulator

736271

4 FM modulator

Description

FM synthesizer to study frequency- and phase-modulation (FM and PM), having the following properties:

Digital, voltage-controlled oscillator (VCO) for generating the FM signal
Voltage-controlled phase shifter to generate the PM signal
4-digit 7-segment display for displaying the carrier frequency
Five channels with channel selection via incremental encoder

A powerful microprocessor gives the device easy handling and digital precision.
