Question

Mandy the Medical Student is building her own ECG (ElectroCardioGram). She has set up the leads and is getting a signal with magnitude up to 5 mV. She would like to filter the signal to only capture signal in the frequency range from 1 Hz to 40 Hz. She would also like to amplify the signal to have magnitude up to 1 V, so that it can be captured by the sound card on her computer. Produce a design for the active filter that will provide the necessary filtering and gain required for Mandy's needs.
