Bộ thực hành diều chế PAM sử dụng trong thực hành thí nghiệm ngành điện tử

Pulse amplitude modulation (PAM) is achieved by sampling an analog signaal. It serves as a preliminary stage for generating PCM signals. The sampling procedure itself supplies PAM of the first type (natural PAM). A sample&hold stage is required additionally for generating PAM of the second type. The training panel contains all the units required for setting up a 2-chanel time-MUX system:

  • 2 x anti-aliasing filters
  • 2 x samplers
  • 2 x s&h stages
  • 1 x multiplex control

A variable duty cycle and a freely selectable sampling frequency allow practical measurements of pulse sequences. Verification of the sampling theorem after Shannon including a display of oversampling and undersampling. Investigation of multiplex control in 2-channel mode is possible.
