Abstract
Official abstract text for this publication.
A tone detection arrangement and method decodes an incoming data stream that is received in sequential bit times and which contains at least one tone that is selectively present for the duration each bit time. Each one of a plurality of digital filters is tuned for detecting the tone over a filter interval. The filters are operable in timed relation to one another.
First claim
Opening claim text (preview).
What is claimed is: 1. A tone detection arrangement for decoding an incoming data stream that is received in sequential bit times and which contains at least one tone that is selectively present for the duration of each bit time, said tone detection arrangement comprising: a) a plurality of digital filters each of which is tuned for detecting said tone over a filter interval that is at least approximately equal in duration to the bit time from a filter start time to a filter stop…
