_______________ detect sensory inputs such as pain and have their cell bodies in the dorsal root ganglion located along the spinal column outside the CNS and are considered peripheral. 

A digital signal sampled at 48kHz is to be downsampled to 12kHz. The bandwidth of the anti-aliasing filter in terms of normalized frequencies in rad is:

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

The causal filter y(n) = x(n) + 0.8 y(n-1) is excited by white noise with

Let  h1(n)=  δ(n-4) – δ (n-7)  and   h2(n)= (-0.8)n-1u(n-1) If the overall system is given by h(n)= h1(n)*h2(n)    where * denotes convolution   The transfer function of the overall system H(z) will be:

The filter H(z) = 9 – z-1 + 3z-2 is excited by white noise of zero mean and unit variance.  The variance of the output will be:

Give the poles and zeros of the causal filter represented by the difference equation: y(n) = 2x(n) + 2x(n-1) + 2x(n-2)

Among the Butterworth, Chebyshev, Kaiser, and Elliptic digital filter design methods, which is likely to meet design specifications with the lowest order transfer function?

For the following signal x(n),  determine the value of the following DFT function X(k) at k=0 and for N=512 without computing explicitly the DFT sum. x(n) = 9δ(n) +  4δ(n-1) – 4δ(n-15) + δ(n-136) X(0) is equal to?

A line segment has a slope of m = 3. It passes through the points A(2, 5) and B(4, k). Determine the value of the missing y-coordinate, k. k = [____]
