Several low order rational transfer functions have been found which approximate a matched filter for a rectangular pulse. These transfer functions are optimum in the sense that the ratio of peak-signal to rms-noise at the output is maximized to the extent allowed by the available parameters. Normalized transfer functions are given and their frequency and time response are shown graphically. For the most useful cases, realizations normalized in impedance and pulse duration are given which allow the use of lossy inductors. A short discussion of a bandpass realization is presented. A transfer function with zeros restricted to the omega-axis is given, along with its realization, which is useful as the lowpass prototype of a bandpass, crystal matched filter.
