qrs detector
Hey,
Does anyone have any ideas on how to design a pure analogy QRS detector?
was thinking of something like this.....
Say if R peak = 1mV
With both P and T <1mV
Assume a gain of around 1000 with the ECG amp output.
Use a multiplier to multiply out the P and T to nothing, with no change in the QRS wave. I.e. Vin^4 = Vout
Then a half wave rectifier and a comparator to flatten out the pulse, and give it the +5V characteristics.
Is there a simpler way?
