Sferic Signal Simulator Circuit Diagram


Sferic signal simulator is applied to develop an impulse  signal which models the waveform of a sferic, a radio atmospheric signals developed by a lightning strike. In time domain, the waveform of a sferic signal is a single high amplitude spike. As this pulse is examined in frequency domain, it will demonstrate a wide band spectrum ranging from few kilohertz to several tens of kilohertz. Here is the schematic diagram:
