Analog Pulse (PAM,PWM,PPM) Modulation & Demodulation Unit
Technical Specifications

  • On board Input signal (Sinusoidal): 1khz, 2khz and Non-sinusoidal (Variable Amplitude)

  • On board Sampling Frequencies: 4khz, 8khz, 16khz, 32khz (Switchable)

  • Modulations & Demodulations: PAM (Natural & Flat Top), PWM and PPM

  • Reconstruction of PWM using RAMP generator Variable pulse widths

  • Voice interface to study the performance of PAM, PWM, PPM modulation & demodulation

  • Inbuilt channel simulator to induce noise, attenuation and bandwidth

  • Reconstruction using low pass filters

Model - DCLT 007
