Abstract :
The two-dimensional spectrum is used to compute the optimum low-pass filter bandwidth for the detection of a pulse in noise having an exponential variation of the spectrum level. A simple equation for the two dimensional spectrum of the input is derived. The resulting equations are used to compute curves showing the time variation of the optimum filter bandwidth and the variation of the output signal-to-noise ratio.
