4046

Busy with the 4046 to try to find the self resonance frequency from a L/C combination and lock that frequency to get maximum output. What I did: By selecting R1 and C1 create Fc and with R1 make pin11 2.5 Volt The Loop filter for PC2 on pin 13 has a 90 degree phase difference to lock better...

Hello Everyone, I am trying to control different speed at precise rpm of bldc motor using PLL with IC 4046. So far I was unable to do it. Can you please suggest me any books, methods, guide to study and implement precise speed control BLDC motor. Thank you.

Hello everyone, First of all sorry for my bad english. I want to simulate on Proteus FM demodulation with 4046. I know that the center frequency Fo depends on the value of R1 and C1. I try to do this application circuit and it doesn't work too: I try to change the value of Fo according to the...
