Re: 4046 lpf design
thanks for your reply, I've determined the parts for r2,r1 and c and i've built the circuit. My problem is the loop filter. do i calculate the values of the filter to give the bandwidth e.g f=1/(2pi*CR)?
I've read loads of stuff and none of it seems to make sense? I must be...
4046 lpf design
I'm currently designing a phase locked loop using a CD4046, MY FMIN is 250kHz and FMAX is 500kHZ, centre frequency 375kHz. I need to know how to calculate the components for the LPF.
I know that f=1/(2pi*RC), but what considerations do I take?
Thank you in advance for any help...
perhap you havent defined value or temp in your code as the rest of the code is straight forward C or it could even be something with the bracket aound
=(unsigned char*)_Value; , these are just guesses as i'm newish to C
Hi there, I'm very new to PIC microcontrollers and have a only a very limited knowledge of programming in C. Does any one have source code and possibly schematics for a circuit using a PIC to read a voltage and then display it on a LCD as a Current reading(Basically an ammeter). Thank you to any...
