A real and odd periodic signal x[n] has fundamental period N = 7 and FS coefficients X [k]. Given that X [15] = j, X [16] = 2j, X [17] = 3j. The values of X [0],X [1], X [2], and X [ 3] will be
Since the FS coefficient repeat every N. Thus
X[1] = X[15], X[2] = X[16], X[3] = X[17]
The signal real and odd, the FS coefficient X[k] will be purely imaginary and odd. Therefore X[0] = 0 X[1] = X[1], X[2] = X[2], X[3] = X[3]
Therefore (D) is correct option.
Consider a signal x[n] with following facts
1. x[n] is a real and even signal
2. The period of x[n] is N = 10
3. X [11] = 5
Since N = 10, X[11] = X[1] = 5
Since x[n] is real and even X[k] is also real and even.
Therefore X[1] = X[1] = 5.
