PLEASE HELP ME:
I'd like to get the peak value of a signal of frequancy about 50 Hz and i got a schematic with the LM393 but it doesn't work. . . . . .
Another question I used the LM 339 as an "Acceptable voltage tester" in order to test if the voltage is in the accepted range or know and that circuit worked well with DC but when I used it with AC via an RC and bridge rectifier i found that the voltage refernce i made before "using potential devider" changes "flactuates" with the input rectified signal so what can i do please help me soon . . . .
Thanks
