Gated Integrator


A gated integrator (also called a boxcar integrator or averager) integrates an analytical signal over a fixed time window. In pulsed experiments the integrator gate is synchronized with the analytical signal by a trigger. This method increases the signal-to-noise ratio by recording the voltage only when the signal is present, and ignoring time periods when there is no signal and only noise.
