ABSTRACT:
A device for correcting the frequency response of an electromechanical transducer, thus allowing said transducer to be used over a wide frequency band and set at or near its resonance frequency. The device includes a delay element having substantially the inverse transfer function of said transducer. An amplifier may be connected between said transducer and said delay element. Said delay element may comprise a variable delay line such as an adjustable length of coaxial cable, and may also include an integrated delay line.
