Fig. 2-7. Derivation of composite
stereo signal showing unbalance and
phase shift errors
The test arrangement for measuring channel
separation is as illustrated in Fig. 2-6, except that the
wave analyser is now replaced by an oscilloscope, and
the procedure is as follows :
(1)
Set up the equipment and modulation meter is
already described for distortion measurements.
