Pseudo-Gaussian Transfer Functions with Superlative Baseline Recovery

The transfer function comprised of (2n+1) poles unit spaced in the ¿ direction on the line s=-D in the s plane is analyzed in the time domain and shown to have the response Fn(t)= Cne-Dtsin2n(t/2), providing a clean pseudo-gaussian pulse. If D=1.5, the after-pulses gre theoretically down by about a factor of 8 × 10-5 and are experimentally acceptable. Experimentally, such an analog signal processor (D=1.5, n=3, unit time = 20 us.) shows excellent shift vs. input rate.
