how to convert a voltage signal at a high frequency of 1Mhz or so to a low frequency of 50hz???
**The amplitude of the voltage wave should remain almost the same..
thanks in advance
also plz mention the numbers of the chips if any.
You want to change voltage to frequency or you want a frequency divider from 1MHz down to 50Hz ? The input frquency wave form is of what type and which wave form you prefer on output?
What you want is a counter: each clock period counter value increases with 1. With a binary counter, the lowest significant counter bit toggles between 0 and 1 at half the frequency you input as clock. Next bit at 1/4th of input frequency, next bit at 1/8th of input frequency, and so on. For example see the timing diagram on this page.
For example with CMOS 4040 type: if you input 1 MHz clock signal, Q1 would output 500 kHz square wave, Q2 would output 250 kHz, etc.
You could use a decade (decimal) counter for 10:1 frequency division. There's many counter types around, to find, check these lists on Wikipedia:
Hi
I'm designing a square loop for carrier recovery,it use a pll,output of pll is a signal with 2fc and i want to divide this frequency to fc ,i would appreciate if anybody can help me with matlab code.
