Unformatted text preview: What is the maximum FIR order? Response At 44.1 kHz, the maximum filter cycle in on the order of T =2.25*10-5 sec. There are about 225 100ns time-slots in the T interval. The maximum FIR would therefore be on the order of N=225 – 20 -5 = 200. While filters of this order have been designed, generally FIR’s have orders from ranging 16 to 64. 1...
