Figure A-3. Components of System Gain
28348-DSH-001-B
Transfer Function Closed Loop
The phase detector gain is 3 volts per
cycle of input.
The low-pass filter contributes one pole
and one zero.
where:
in
The gain for the system involves the phase detector, the low-pass filter, and the VCO.
Figure A-3
1/16
shows the system with these three components broken out.
