Abstract :
Automatic gain control circuits are provided in analog seismic amplifiers to give more or less a constant output with varying input signals. Present available analog seismic amplifiers use vacuum diodes or photo-resistors as AGC losser elements. The suitability of CIL make junction diodes, Holland make photo-resistors and GEC make thyrite as AGC losser elements, is discussed in this paper.
