MA-1000
Moving Averager
● For EMG and ENG measurements
● Uses easily replaceable time constant modules to implement the moving average
● Comes standard with time constants of 50, 100, and 200 mS, but any values between 10 and 500 mS are available
The MA-1000 consists of an adjustable-gain input buffer, a precision full-wave rectifier, and a moving averager circuit. It is used for the accurate quantification of electromyogram (EMG) and electroneurogram (ENG) signals. The moving averaging circuit is a 3rd order Paynter low-pass filter that creates a contoured or smoothed envelope around the rectified signal, with selectable degrees of smoothing. Smoothing is accomplished by the selection of a time constant, conveniently implemented by front panel pushbutton switches.
