A Solid State Logarithmic Video Amplifier for Pulse Applications

摘要

A logarithmic amplifier has been designed for a datasampmampling system used in connection with a radar system. The amplifier was designed primarily for pulse inputs of positive polarity with a pulse width of 1 to 2 microseconds and a pulse repetition frequency of 5.46 kc. One outstanding feature of the amplifier is its simplicity. The design incorporates no complicated feedback arrangements to achieve the desired logarithmic characteristics. (Author)
