2.1.5 Channel separation in Stereo reception for the stereo television set
a) TV setup in PP condition.

Note:
üDisconnect the speakers for more comfortable work.
e) Adjust the stereo generator for left channel only – with 30% modulation of 300 Hz sine
wave and 7.5 kHz deviation.
f) Read the Double Voltammeter value Vac corresponding of Left and Right channel and
calculate the stereo separation trough the equate:

g) Adjust the stereo generator for left channel only – with 30% modulation of 3kHz sine wave
and 7.5 kHz deviation.
Sep (3kHz) L
