October 26, 2000
due November 2, 2000

assignment:
   a> implement filters and filter cascades in Matlab:
       DSP First, Lab C.5.3 (pp. 459-462)
       - skip C.5.3.2 question 7, p. 460
       - visualize spectra in C.5.3.5 using spectrograms
	 (don't sketch by hand)
   b> write a Matlab function which takes an input vector x
       and a vector of FIR coefficients b and returns the output
       vector y as y=myfilt(b,x).
       - compare the operation of your function to Matlab's firfilt
       - compare the performance of your function to firfilt
