FM modulator

LD 736271
FM modulator
  4  FM modulator


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.
