Thank you for your response. Actually I need a Simulator circuit which act as a source of ECG signals same as natural ECG complex. We can test an ECG amplifier without connecting to a person . This way we can check the performance of our ECG amplifier. Regards, Jiten Pandya.
Take a data file containing a sampled real life signal, use a microprocessor, and put it through a DAC. If you have access to an arbitrary waveform generator, it will save you some work. There will be data files of an ECG on the net. An attenuator will give the desired voltage. Cheers, Richard
