a) \(\frac{1}{N} \sum_{n=0}^{N-1}x(n)e^{j2πkn/N}\)
b) \(N\sum_{n=0}^{N-1}x(n)e^{-j2πkn/N}\)
c) \(\frac{1}{N} \sum_{n=0}^{N+1}x(n)e^{-j2πkn/N}\)
d) \(\frac{1}{N} \sum_{n=0}^{N-1}x(n)e^{-j2πkn/N}\)
b) \(N\sum_{n=0}^{N-1}x(n)e^{-j2πkn/N}\)
c) \(\frac{1}{N} \sum_{n=0}^{N+1}x(n)e^{-j2πkn/N}\)
d) \(\frac{1}{N} \sum_{n=0}^{N-1}x(n)e^{-j2πkn/N}\)
