A call on line 2 completes when both switches are in position B. To
use both lines, the switches alternate between positions A and B.
When the switching rate is low, both transmissions become garbled and
Increasing the switching speed clarifies the
By increasing the switching speed to a rate higher
The circuit shown in figure 1-4 is a simplified 12-channel TDM
The two switches rotate in synchronism and sample each
channel once during each revolution. The 12 samples are in each time
frame. By increasing the rotation speed above voice frequency, very
little distortion occurs and all 12 conversations are intelligible.
