Transmission lines 21, 22 and 23 having the same impedance as couplers 1 and 2 are connected to terminals 12', 13' and 14' where the incident wave from terminal 11 is distributed equally and appears. Lengths l1 and l2 of line 21 and 22 are set to satisfy (l/6+a)lambda and (l/12+ a)lambda respectively (however, lambda is wave length and l is length of line 23 and is equal to alambda). When loads having the same impedance are connected to terminals 24, 25 and 26, the incident wave from terminal 11 generates reflection waves of the same amplitude at terminals 24, 25 and 26 and is input to copulers 1 and 2. Then, all reflection electric power is distributed to terminals 15 and 16 equally and appears and is absorbed by matching loads.

Title: Driving method of noncyclic filter
Inventor: ENOMOTO TADAYOSHI
IPC: H03H15/02
Filed: 1980-04-30
Abstract: PURPOSE:To eliminate completely the missampling, by using two noncyclic matched filters and then securing a difference of 180 deg. for the sampling phase between both matched filters. CONSTITUTION:The closing timings of switches 23 and 24 are shown by the arrows 31 and 32 in the diagram and given with every fixed period T with a difference of phase by 180 deg.(T/2). These two output signals are added 25 together, and an output waveform is obtained through the terminal 22 as shown in figure 33. When the switches 23 and 24 are closed with the timings as shown by the arrows 37 and 38 in the diagram, the timing of arrow 38 equals to the rise and breaking times of input signal 30 to cause a missampling. Thus the output signal of filter 40A becomes indefinite. On the other hand, the value of input signal 30 is within a certain period with the timing of arrow 37, and thus the output signal of filter 30A is set at a desired value. Thus the output signal of the noncyclic matched filters can be obtained with timing 39.
