Electric power spectrum display procedure in spectrum analyzer, involves averaging electric power value for every frequency sweep and performing logarithm conversion of mean power value for every display point

摘要

Logarithm amplification of received signal is done. Amplified output is detected and converted into digital value which is subjected to antilog conversion for every display point (i) in the frequency sweeping width. Electric power value for every sweep is averaged and logarithm conversion of main power value for every display point is done. An Independent claim is also included for spectrum analyzer.
