The NL703 EMG Integrator module was designed to produce an analogue signal to represent the amount or strength of muscle activity. The unit accepts signals up to +1V, which are first full wave rectified and then applied to a "leaky integrator" within the module. The output of the integrator is buffered and the overall gain is set at unity. The time constant of the integrator is selected by a 6 position rotary switch. A toggle switch is also provided so that the direct signal can be viewed.
