illustrates the waveforms in step 11 expanded to show relative timing. the
second and fourth traces are delayed by 5 ms from the first and third. The oscilloscope
settings are changed as follows:

13. Figure
10-8
illustrates the waveforms of properly working line generators. Whenever there
is a pulse on TP2 (or
TPl),
the appropriate integrator U201B (or U203B) generates a
ramp (the output vector) which feeds back to U201A (U203A) and shows on its output.
