Abstract : The patent describes a solid state logarithmic amplifier and limiter device using seven logarithmic stages to achieve a 70 db logarithmic range. Without the use of vacuum tubes or diodes, the input voltage is attenuated and amplified in separate channels to produce seven logarithmic currents which are summed to produce the log amplified and limited output.
