setting up the TDM generator model:
use the bit clock to externally synchronize the oscilloscope.
observe the Q1 output, and adjust is width τ to about 10µs
observe the Q2 output. It will have the same width as Q1. Move it, with the DELAY control,
so its separation from Q1 is about10µs
setting up the TDM demultiplexer model:
set the TUNEABLE LPF to a bandwidth of about 3 kHz
set the width of the Q2 output to about 10µs
connect the TDM to the multiplexer INPUT.
while observing the TDM on one channel, and Q2 of the demultiplexer on the other, move
the Q2 pulse under either one of the two TDM channels.
observe the recovered message at the output of the demultiplexer.
what is the significance of:
• the pulse width at the TDM generator
• the pulse width at the demultiplexer
• the spacing between pulses
