ABSTRACT:
A signal waveform equalizing circuitry for compensating for the distortion of a signal picked up from a magnetic recording medium by means of a magnetic head, including a first network having the transfer function of (1-BS) and a second network made up of passive elements having the transfer function of a multiplication of the transfer function (1+AS) and the transfer function having the integration function, wherein said first and second networks are serially connected. Thus, the circuitry having an overall transfer function which is a multiplication of transfer functions expressed by (1+AS) and (1-BS) respectively (A, B being a constant, and S being j.omega. while .omega. is angular frequency) and a transfer function having an integration function is realized using relatively simple circuit configuration.
