Product Category : Signal Conditioners
VPL Infotech & Consultant offers Pulse Amplitude/Width/Position Modulation Kit. VPL Infotech & Consultant designs and manufactures merchandising device programmers, device testers, etc. Pulse Amplitude/Width/Position Modulation Kit, model VMC-PAM/PWM/PPM is a single board unit to provide facility for experimentation in the area of Pulse modulation & Demodulation techniques such as PAM, PWM and PPM. The onboard sine wave generator provides four synchronized amplitude variable sine waves. The unit also accepts external sine wave frequency. This Pulse Amplitude/Width/Position Modulation Kit provides natural and flat top sampling with sample and hold outputs.
In this kit, one can study Pulse amplitude, Pulse width, Pulse position Modulation/ Demodulation using natural sampling and flat top sampling. One can also perform voice communication using above pulse modulation and Demodulation techniques. The kit can also be connected with other communication kits from VPL to perform related experiments. All the relevant test points are brought out onboard.
