Two 4-point  FFTs and a 4-point  IFFT  are used to perform fast convolution of the sequences x(n) and h(n) (N = 4) h(n) =4δ(n) + 6δ(n-1) +2δ(n-2) +7δ(n-3) x(n) =u(n) – u(n-4) The result y(n) for n=1,2,3,4  after the IFFT is equal to

A N-point DFT (N=16) requires N2 complex multiplications. If this N-point DFT is performed by combining the results of two (N/2)-point DFTs, the number of complex multiplications required is:

Give the steady state response of the causal filter H(z) to the input x(n)=3 sin(πn/6) H(z) = 2 + 2z-6 The steady-state response of H(z) is:

For the signal x(n) shown below,  determine the value of the following DFT sum function for N=128 without computing explicitly the DFT sum. x(n) = δ(n) + 2δ(n-1) – 9δ(n-12) + 13δ(n-50)

Give the expression for the ideal impulse response of a bandstop filter with cutoff frequencies at 5 kHz and 7.5 kHz. The sampling frequency is 30 kHz.

A line is written in Standard Form: 4x – 2y + 12 = 0. Convert this equation to Slope-Intercept form (y = mx + b) to identify the slope and y-intercept.

The graph of the parent line y = x is shown as a red line. A blue line is drawn that represents a translation of this parent line. If the solid line has a y-intercept of -3 and is parallel to the dotted line, what is its equation?

Match the transformation description to the correct coordinate rule.
