The slew tile performs the basic function of slew limiting or integration. The result is an output response that lags the input thus slowing down the transition from one voltage to another. The slew limiter is essentially the same structure as a simple low pass filter, but has been tuned to operate on much lower frequencies, and is designed to be used on control voltages. . On the rear of the unit is a dip switch which sets the slew range from slow to fast.
