It has been amply demonstrated
that signal tracing can follow a signal
from its first feeble flutter on the
antenna to its final full force at the
speaker. Signal tracing can determine
whether the signal remains within the
prescribed channels as a well-behaved
signal should or whether it goes out of
bounds. Signal tracing can track down
unwanted signal voltages and aid in
their elimination.
Rather, it is the radioman that does all this. The hand that moves the probe must be guided by an intelligence that knows the function of each part and its relation to every other part. Signal tracing is a happy union of ingenious instrumentation with high intelligence. |
