Claim Text:
1. A method for automatic gain control, said method comprising: (a) detecting a portion of an input signal corresponding to a measurement window associated with a predetermined time interval; (b) determining a peak value of said input signal in said detected portion of said input signal during a first predetermined time segment within said measurement window; (c) determining a number of occurrences of said determined peak value of said input signal during a second predetermined time segment within said measurement window, wherein said second predetermined time segment is greater than said first predetermined time segment; (d) comparing said determined number of occurrences of said determined peak value of said input signal with a predefined range of occurrences for identifying a speech portion of said input signal corresponding to said measurement window upon said determined number of occurrences of said determined peak value of said input signal being within said predefined range of occurrences, and for identifying a non-speech portion of said input signal corresponding to said measurement window upon said determined number of occurrences of said determined peak value of said input signal being outside said predefined range of occurrences; and (e) adjusting a gain corresponding to said first predetermined time segment of said input signal based on said determined peak value of said input signal, upon identifying said speech portion of said input signal.
