saleheen said:I tried using LM741 but it is not able to do the job.
saleheen said:1) The frequency is between 36 kHz to 44 kHz. Fc=40kHz, fm=4kHz. Therefore, the signal outputs are fc+fm, fc-fm and fc.
2) The LM741 is only able to generate the same signal. unable to amplifly it.
Initially, I was using LM7121 (as in the attached diagram) but I was not able to get any signal at the output.
saleheen said:Hi flyingSky, Actually I am not able to get any signal from the buffer.. The signal from the AM is lost probably due to noise.

saleheen said:When I test the circuit using a oscilloscope, I don't get any signal. As in, good as nothing connected to the oscilloscope.
saleheen said:When I replace the AM signal to a functional generator signal, I am able to get the output signal from the buffer. Is it due to some interface between the AM and the buffer ?
