A pulsed integrator for EMG analysis.
A novel device is described which converts EMG signals to an output which is proportional to the area under the rectified curve in discrete time intervals. This is achieved by resetting a long time constant integrator at the desired rate and saving each integral in a sample/hold circuit for output during the subsequent integration period. This output is particularly useful for quantifying fast reflex events since the signal is integrated without leakage in each period and leaves no residual signal in subsequent periods.
