Crest factor, which is the peak to RMS ratio of a dynamic
signal, also effects the required C
AVE
value. With a higher
crest factor, more of the energy in the signal is concentrated
into a smaller portion of the waveform, and the averaging
has to ride out the long lull in signal activity. For busy
waveforms, such as a sum of sine waves, ECG traces or
SCR-chopped sine waves, the required value for C
AVE
should be based on the lowest fundamental input frequency
divided as such:

using the same design curves presented in Figures 6, 8,
16 and 17. For the worst case of square top pulse trains,
that are always either zero volts or the peak voltage, base
the selection on the lowest fundamental input frequency
divided by twice as much:

The effects of crest factor and DC offsets are cumulative.
So for example, a 10% duty cycle pulse train from 0V
PEAK
to 1V
PEAK
(CF = 10 = 3.16) repeating at 16.67ms (60Hz)
input is effectively only 30Hz due to the DC asymmetry and
is effectively only:

for the purposes of Figures 6, 8, 16 and 17.
Obviously, the effect of crest factor is somewhat simplified
above given the factor of two difference based on a
subjective description of the waveform type. The results
will vary somewhat based on actual crest factor and
