hi all
just a quick question. i have built a circuit
in NI software. and there are various virtual
bench tools. one of which is an oscilloscope.
i have used it to measure the output of an
LM358 which amplifies the input of an electret
mic. initially i thought i was only getting a reading
of about 50 odd mV, however i now think i should
have taken the measurement above and below the
zero line. i believe this is called peak to peak?
reading Pk-Pk gave me a total of 125mV. so is
the Pk-Pk the correct reading or is it only whats
above the zero line thats inportant. i also set the
osci' to AC rather than DC for the reading.
Regards
Fenris
