Frequency Multiplier and Frequency Divider Explained

Frequency Divider and Frequency Multiplier Circuit (from 2 to 100 times) using IC 4017 and IC 4046 (PLL)
The output waveform will be square wave only (used for digital signals) and max. output frequency is 1Mhz.

Excellent animated video 👍👍 Thank you very much sir 🙏

You are the best, best mathematical circuit dividing and multiplying tutorial ever, specially the information about the addition of the divider to the feedback to multiply it, can you please confirm this to me and others, when you add the divider in the feedback loop, this create new frequency, does combining 2 different frequencies multiply the output frequency or its the alternating change of the frequency cause the multiplication or the 2 statements are true? 😊 Trillion thanks 💙

1 - what is the name of the blue part can add wire to it
2 - i want to create rf remote controller i only have 60mhz crystal can i use your frequency multiplier to get higher frequency

i know understand how a RPM Gauge works on a tractor using the Alternator AC Output Frequency before the current gets Rectified to DC.
