Abstract:
1. A signal shaping circuit, comprising: an operational circuit that provides weights to a first signal input to a first input element and a second signal input to a second input element, adds or subtracts the second signal to or from the first signal, and outputs a signal obtained by adding or subtracting the second signal to or from the first signal; a divider that divides the signal output from the operational circuit into signals, causes one of the divided signals to be input back into the second input element of the operational circuit, and outputs the other of the divided signal on a downstream side of the signal shaping circuit; a delay element that delays the signal output from the operational circuit and to be input to the divider or the signal output from the divider and to be input to the second input element; and an adjuster that adjusts at least one of the weights provided to the first and second signals at the operational circuit.
