Determine the output frequencies of the two plls- determine


Two PLL configurations are shown in Figure. Assume the SSB mixer adds its input frequencies. Also, assume f1 is a constant frequency provided externally and it is less than fREF. The control voltage experiences a small sinusoidal ripple with a frequency of fREF. Both PLLs are locked.

(a) Determine the output frequencies of the two PLLs.

(b) Determine the spectrum at point A due to the ripple.

(c) Now determine the spectrum at nodes B and C.
