OSTI ID:4085523
An all solid-state logarithmic video amplifier that develops output pulse amplitude proportional to the logarithm of the input pulse amplitude is described. The resultant compression reduces the ratio of maximum to minimum signal amplitude from 3,000:1 at the input to 10: 1 at the output thus allowing the pulses to be viewed on a oscilloscope or recorded on magnetic tape. Conversion accuracy is such that from observations of the output pulses, the amplitude of any signal within the 70 db input range may be estimated to within 3 db. (auth)
