Note: The total detection bandwidth covers the frequency range of fO +Df

Normally,
j = 0.5 is recommended.

Increasing C1 improves the out-of-band signal rejection, but increases the PLL capture time.
e) Calculate value of the filter capacitor CD . To avoid chatter at the logic output, with RD = 470KW, CD must be:

Increasing CD slows down the logic output response time.
