Hi !!!!!!! guys
Special thanks to IanP
and thank you A. Anand Srinivasan
Now can I share a new problem,
I am using a ultra sound transducer as input to a ckt as shown in attachment;
The required signal is sine wave of pk-pk volt 50mv;
and output of the circuit is dc of 6-8V as shown in attachment;
Now as you guys know that even noise in the envirionment can have sine wave of pk-pk amplitude 50mV.
Now the problem is I always get output 6-8V.
So,I am finding hard to discriminate the noise even if I am using low noise amplifier LM833.
So how to make output go to minimum DC when there are noise same as signal.
Any ideas guys@!??
