PAM - PPM - PWM Modulation and Demodulation

Model: 7410

PAM-PPM-PWM are the basic pulse modulation techniques. The trainer provides complete set up to the students for performing experiments on the techniques. They can study sampling, pulse modulation, demodulation and signal reconstruction processes. Separate circuits are provided for each technique. The student workbook and operating Manual provides technology details, circuit description and experiments.
