Hi, can anyone please help me in solving this question,
Design an operational amplifier circuit for a signal conditioning application,where the signal of a microphone is conditioned for an AD-converter.
-Microphone signal peak-to-peak value is 122mv.
-Microphone signal has zero-bias, i.e itvaries equally on both sides of zero
-Microphone output impendance is 600 Ohms
-AD-converter has 0 V to 2.5 V input voltage range
-AD-converter has a 2.5 V reference voltage output on chip,which you can use in biasing circuit
-AD-converter input impendance is 10 KOhms
-The total signal attenuation on the system should be less than 1% ( = 99% of the optimal signal strengh remains)
2.design an anti-aliasing filter for the previous application taking into account the following requirement and properties:
-the application requires that the signal power spectrum has minimal amount of spectral distortion
-signal information bandwidth is 122Hz
-signal has white noise at level -40dB
-sampling rate is 444100s-1
-AD-converter's resolution is 12 bits
thnks in advance
