(c) Generalize the results in parts (a)and ( b )for N = 2". ( a ) For an eight-point decimation-in-time FFT,we may count the number of complex multiplications in the flowgraph given in Fig. 7-6. In the first stage of the FFT, there are no complex multiplications, whereas in the second stage, there are two multiplications by W:. Finally, in the third stage there are three multiplications by W x ,w;, and W:. Thus, there are a total of five complex multiplies. ( b ) A 16-point DFT is formed from two &point DFTs as follows:

where G ( k ) and H(k) are eight-point DFTs. There are eight butterflies in the last stage that produces X ( k ) from G ( k )and H(k). Because the simplified butterfly in Fig. 7-5(b)only requires only one complex multiply, and noting that one of these is by WP, = 1, we have a total of seven twiddle factors. In addition, we have two 8-point FFTs, which require five complex multiplies each. Therefore. the total number of multiplies IS 2 - 5 + 7 = 17.

( c ) Let L ( v ) be the number of complex multiplies required for a radix-2 FFT when N = 2". From parts (a) and (h) we see that L(3) = 5 and L(4) = 17. Given that an FFT of length N = 2"-' requires L(v - I) mul~iplies.for an FFT of length N = 2", we have an additional 2"-I butterflies.

[CHAP. 7
The decimation-in-time and decimation-in-frequency FFT algorithms evaluate the DFT of a complexvalued sequence. Show how an N-point FFT program may be used to evaluate the N-point DFT of two real-valued sequences.
As we saw in Prob. 6.18. the DFTs of two real-valued sequences may be found from one N-point DFT as follows. First, we form the N-point complex sequence
After finding the N-point DFT of .r(n). we extract X I ( k )and X z ( k ) from X ( k ) by exploiting the symmetry of the DFT. Specifically.

Let g ( n ) be a real-valued sequence of length 2N. From this sequence. we may form two real-valued sequences of length N as follows:
From these two sequences, we form the complex sequence
Computing the N-point DFT of . r ( n ) . we niay then extract the N-point DFTs of x , ( n ) and x 2 ( n ) as follows (see Prob. 7 . 7 ) :
x ~ ( k= i [ ~ ( k ) X * ( ( N - k ) ) ~ ] ) x ~ k = ; [ x ( k ) - x * ( ( N - k ) ) NI )
Now all that is left to do is to relate the 2N-point DFT of g ( n ) to the N-point DFTs X l ( k ) and X , ( k ) . Note that
Therefore,
