A frequency synthesizer has a crystal reference oscillator of 15 kHz followed by a multiplier with a factor of 100. The variable-modulus prescaler has M = 64/65. The A and N up-counters have factors of 67 and 276, respectively. What is the synthesizer output frequency?

This is a practice question from my Introduction to Circuits course. I am having a hard time finding the poles for this. When I implement the circuit in LT Spice, I can see that the cutoff frequency is somewhere around 16kHz, but I can't figure out how to come up with that value mathematically. It is underdamped; so, will have imaginary components, but I'm lost as to how to find them or what to do with them or how to come up with the correct cutoff frequency to match LT Spice. Thank you for your assistance.

Nowadays switching power supplies are commonly used because they offer better efficiency and smaller size compared to a linear power supply, because high switching frequency allows for smaller transformers. One place to find a SMPS (switching mode power supply) is a phone charger. Switching power supplies cause high frequency noise on switching transients. The noise on the output is filtered in various ways but savings may be considered on the output filter (extra inductors and capacitors = extra costs), which means the output will have some amount of noise left getting to the device via the USB cable. Estimate the frequency where the phone charger starts to act as an antenna when the USB cable length is 1.9 meters. Submit your answer in MHz without the unit, rounded to one decimal place. Hint: Either "rule of thumb" can be used.
