indicated high-frequency boost in an
amplifier accompanied by a lightly damped " s h o c k "
trasient. The sinuoscidal type of diminishing oscil-
lation along the top of the square wave indicates a
transient oscillation in a relatively high " Q " network
in the amplifier circuit. In this case, the sudden
transition in the square w a v e potential from a
sharply rising, relatively high frequency voltage, to
a level value of low frequency voltage, supplies the
energy for oscillation in the resonant network. If
this network in the amplifier is reasonably heavily
damped, then a single cycle transient oscillation
may be produced as indicated in
Fig. 38.
