Hi Thanx for your replies. I have gone through a good Article found on web. It says that no single value of "N" can meet the ITU-T specs and also gave reason for this. That why two values are needed. It has taken N= 106 (13.3msec) for high group and N !2 for lower group frequencies.(two goertzel filters are 106 samples apart). I could not understand the fisrt statement of "No single value of N can meet ITU-T spec and it's explination". Could you people explain this? For reference I am attcaching the document with this mail. Thanx in advance Shehryar | |||
