Can you use microcontroller to generate the output for your clock or do you have to use only digital logic circuit? What I am saying is you can count the frequency of your input clock and generate the output frequency as needed. See image. You will get something like that. Will your clock be synchronized with some other circuit also?

The modulator can be either descrete-time (switched-cap) or continuous-time (e.g gm-C) or even both (some stages descrete, some continuous).
The decimation filter is a digital circuit, that means FFs and logic.

If you have good knowledge about microcontrollers, your project can be done easily. Most of them have A/D converters, useful for voltage and current measurement. They have also all sort of timers and counters inside, useful for pulse and frequency measurement. uCs associated with all sort of sensors allow you to measure almost everything.

Possible yes, but limited in terms of signal bandwith and dynamic. Assuming you mean an analog signal, the best
way is most likely by digital processing. Previously, magnetic tape loops have been used for delays in the seconds range.

You can separate the analog and digital supplies of your circuit by connecting the analog and digital supply pins to separate nodes, and then joining these nodes at the point closest to your power supply. You can join the supplies with the use of inductors, which will block noise traveling between the nodes. This will reduce noise caused by (...)
