Abstract:

The link c nnection, in the form o a link amplifier with variable transconductances between its grid and plate delay lines, can be used as an adaptive matched filter. On the assumption that the unknown input signal is fixed and repeats every T seconds for a number of cycles, it is shown that the optimum adjustment procedure is to et each tran conductance equal to the average of t e corresponding input sample of signal plus noise. Several types of averagers are discus ed and the RC averager is chosen as the most desirable. Speed of averaging and practicability of instrumentation are the basis of comparison. An electronically controlled, linear, variable-gain amplifier and several ampling system are suggested for t e actual instrumentation of the adaptive matched filter. Author 0
