Decision feedback type automatic equalizer
专利汇可以提供Decision feedback type automatic equalizer专利检索，专利查询，专利分析的服务。并且PURPOSE: To equalize correctly an input pulse signal including a forward interference component independently of the quantity of backward interference component by eliminating the forward interference component from the signal obtained by eliminating the backward interference component of an input pulse signal by a decision feedback equalizer.
CONSTITUTION: A pulse a
1 with distorted waveform is fed to an input terminal. A discriminator 3 compares the output of an adder 2 with a threshold value at a timing 0 to decide whether '1' to '0'. The output pulse (b) of the discriminator 3 is subjected to the multiplication of coefficients C
(1) , C
(2) by multipliers 5-1, 5-2 via delay elements 4-1, 4-2 having a delay time T, becomes signals b
1 ,b
2 , which are returned to the adder 2. Thus, the backward interference component is eliminated from the input pulse a
1 by timing points T, 2T, 3T. The output of the adder 2 is retarded by a time equal to the basic period T of the input pulse by the delay element 7-1 and the result is fed to an adder 8. On the other hand, a multiplier 6-1 multiplies a coefficient C
(-1) with the output pulse (b) of the discriminator 3 to form a signal b
3 . The adder 8 subtracts the forward interference component b
3 from the input pulse signal extracted by the backward interference component.
