Adjustable slope equalizer

摘要

An adjustable slope equalizer is disclosed for maintaining a predetermined output level at a predetermined frequency. An equalizer comprises: an adjustable input means; a first voltage divider means having an output and having an input operatively connected to the low impedance input means; a second voltage divider means having an output and having an input operatively connected to the low impedance input means; an adjustable high impedance means having an output and having at least two inputs operatively connected to the outputs of the first and second voltage divider means; and a SAG correction means operatively connected to the output of the adjustable high impedance means. The output of the SAG correction means has the predetermined output level at the predetermined frequency for any setting of the adjustable high impedance means.
