In the polyphase filter structures for a uniform DET filter bank described in Sec-tion 11.10.1, the polyphase filters in the analysis section were defined by equation (11.10.10). Instead of this definition, suppose we define the N-band polyphase filters for the Iowpass prototype filter, as

(c) Sketch the analysis section of the uniform DFT filter bank.

(d) Determine and sketch the synthesis section of the uniform DFT filter bank.
