Abstract: Apparatus for processing broadband impulses signals of low repetition rate includes a tuner for receiving broadband impulsive signals of low repetition rate and providing an output signal characteristic of the amplitude and spectral content of the received input signal. Resolution bandwidth filters coupled to the tuner output each have a different bandwidth that determines the measurement resolution and influences the sensitivity and transient response to low repetition rate impulsive signals. At least one radio frequency switch selects a resolution bandwidth filter for coupling to and associated one of at least a peak detector, an average detector and an envelope generator. A gate generator coupled to the peak detector, the average detector and the envelope generator furnishes a gating signal to each to provide a peak signal, an average signal and an envelope signal respectively during a selected gating interval. A microprocessor is coupled to the peak detector and the average detector.

Abstract: An automatic power control system for automatic power control of a semiconductor optical amplifier arranged to amplify a signal has an automatic power control loop which provides automatic power control of the power of the amplified signal for maintaining the power of the amplified signal in the output from the semiconductor optical amplifier at a desired level. The automatic power control loop compensates for, an estimated level of amplified spontaneous emission in the detected output power using stored characteristics of the semiconductor optical amplifier. In one type of embodiment, a photodiode detects the output power of the semiconductor optical amplifier and a current detector detects the drive current of the semiconductor optical amplifier and the automatic power control loop uses both the detected output power of the semiconductor optical amplifier and the detected drive current.
