Abstract :
A direct digital method of measuring the noise power in a low-pass random waveform is described. The input-output relationship and the sensitivity of the digital detector are determined. Direct digital measurement of noise power offers a number of advantages in the instrumentation of radiometers and other noise-measuring systems.
