System For Enhancing An Analog Signal

US Patent:
5398286, Mar 14, 1995
Filed:
Jul 9, 1993
Appl. No.:
8/087700
Inventors:
Robert Balestri - Frederick MD
W. Foster Rich - Arlington VA
Stephen M. L. Eng - Vienna VA
Robert B. Lezec - Jove-les-Tours, FR
Joseph P. Pagliuca - Laurel MD
Assignee:
Booz-Allen & Hamilton, Inc. - McLean VA
International Classification:
H04B 1500
US Classification:
381 94
Abstract:
A system for enhancing an analog signal by eliminating undesired portions of a detected signal, such as incoherent, background noise is disclosed. A detected input signal is divided into two paths (P. sub. 1 and P. sub. 2), each path having a high pass filter (50, 52) for removing low frequency noise components beneath the frequency band of the desired portion of the input signal. One signal path (P. sub. 2) is delayed by a predetermined time delay (54) and summed in a summer (56) with the other signal path (P. sub. 1). By shifting and summing the two path signals, the desired signal is enhanced in a number of ways. First, the incoherent, undesired portions of the detected signal within the frequency band may be significantly attenuated or cancelled. Second, the gain of the desired portion of the detected signal is increased. Third, the quality of the desired signal is improved with the addition of a reverberation component.
