In the attenuating preamp circuit below, what is the high pass filter frequency? I know with out the attenuating resistor (R6), it would be 16Hz, but I don't know what the R6 resistor does to it. My thought was, the R5 and R6 are in parallel, in series with R7, making it at 31Hz.
Thank you.
Thank you.
Pin 2 is a virtual earth, therefore R6 and R7 are in parallel. Their combination is then in series with R5.
