Hello ,
I am designing a bandpass filter 60-1000 Hz and envelope detector cut off frequency 500 Hz.
I want to use TL084 as bandpass filter, rectifier and envelope detector. Can you provide me sample circuit for this ? and mathematics how to calculate circuit values.
I am a beginner. Actually i will be using this part of circuit for EMG signal detection.
EMG signal extracted through electrodes is amplified by INA 114 , TL084 then used as band pass filter, rectifier and envelope detector. and at the end OP 177 is used as a comparator. please guide me
Thanks.
