Which Fourier transform is denoted by x(q)?
The discrete-time Fourier transform of x[n] is denoted by X(Q). We generate the periodic signal 9[n] by periodically replicating x[n], i.e., R[n]. (b) Write an expression relating the Fourier series coefficients of 9[n] to the Fourier transform of x[n]. I. Continuous-time Fourier series II. Discrete-time Fourier series III.
