I designed a transistor based amp to amplify a FM stereo multiplex signal. The transistor amp was correctly biased and could amplify the signal from 500mV to 4.5V. I observe this amplification using oscilloscope. Then I was hoping to do digitally DE-multiplex the signal using DSP. After several trials I found that some thing is wrong and try to convert the sampled signal back to analog using DAC. But I found that the observed signal is distorted and only had a peak of 1V.
1) Is this happening due to low output impedance of the amplifier?
2) How can I resolve this?
3) What are the high output impedance configurations?
