Assume that you are asked if equalization is necessary. After making
the necessary calculations you should reply that equalization is
to be performed only after the relative delays at all frequencies
have been determined even though primary delays are in tolerance.
not necessary because the relative delays are within parameters
at the two specified frequencies.
necessary because the average delay and
unequal at the two specified frequencies.
necessary because the primary delay exceeds the
delay for parameter S3.
The circuit conditioner will find that his determination of envelope-
delay distortion is more critical at certain frequencies than at
others. The most critical area (minimum variation) in parameter S3 is
shown by figure 2-7 to lie between the frequencies of
0.5 and 0.6 kHz.
0.6 and 1.0 kHz.
1.0 and 2.6 kHz.
2.6 and 2.8 kHz.
Assume that you switch from the end-to-end method to the end-to-end
with reference return method.
The result is that the absolute
readings you will observe on the DELAY meter of your TS-2669/GCM are
precisely the same in both methods.
less than those in the auxiliary line.
identical to reference delay calculations.
larger than those in the end-to-end method.
