railway RRB JE (CBT I + CBT II) Mock Test 2024 Signals and Systems Discrete Fourier Transform (DFT) and Discrete Fourier Series (DFS) Inverse Discrete Fourier Transform
Inverse discrete Fourier transform of Y(k) = {1, 0, 1, 0} is
1
y(n) = {0, 0.5, 0, 0.5}
2
y(n) = {0.5, 0, 0.5, 0}
3
y(n) = {0.5, 0.5, 0, 0}
4
y(n) = {0, 0, 0.5, 0.5}
