Abstract
Three new double delay‐line filters for pulse amplifiers were developed to circumvent the poor noise performance of conventional double delay‐line filters. The operating principle of the new filters is the alteration of the noise spectrum stored in the delay lines prior to the signal arrival. With one of the new filters, a symmetrical bipolar output pulse was obtained that had a measured noise linewidth of 1.6 keV fwhm Si (189 rms electrons) for 5 pF external capacitance, 4.2 μsec delay‐line length and 1.4 μsec RC integrating time‐constant. The noise linewidth slope was 0.05 keV/pF.Keywords
