Abstract

See full text

A device is disclosed for converting an input signal to a digital output signal at a preselected sampling rate with an increase in dynamic range without aliasing. The preferred embodiment utilizes a converter for producing a low resolution digital signal at a higher frequency and an averaging digital filter arrangement for increasing the resolution at the preselected sampling rate. The device is easily capable of producing digital output signals of at least 17 bits at any frequency such as 48 KHz.
