Dial Pulse Detector
US Patent:
4071708, Jan 31, 1978
Filed:
Nov 11, 1976
Appl. No.:
5/741047
Inventors:
Murray L. Kaplan - Cherry Hill NJ
Terry N. Herbster - Willingboro NJ
Alan F. Holden - Medford NJ

Alan F. Holden - Medford NJ
Assignee:
Telesciences, Inc. - Moorestown NJ
International Classification:
H04G 136
US Classification:
179 16E
Abstract:
A dial pulse detector apparatus accurately detects the occurrence of dial pulses in the presence of adverse line conditions resulting in severe signal distortions due to inductive effects, noise and loading by other pieces of equipment. Signals greater than two different selected threshold levels are examined for, and signals less than the lower threshold are also examined for. Signals greater than the threshold levels are counted up on a time duration basis and added in a weighting arrangement. Signals less than the lower threshold are counted on a time duration basis and are subtracted from the added signals. When the combined signal counts reach a first specified count a dial pulse break signal is recognized. Signal counting is continued and when the combined signal counts reach a second specified count a dial pulse make signal is recognized, thereby completing the detection of a dial pulse. Because of the weighting system it would be possible to erroneously record the occurrence of two dial pulses in a time interval when only one dial pulse could validly occur.
