Extra exam question E7F14

WhyAdding more taps allows a digital signal processing filter to create a sharper filter response. Adding more taps to a digital signal processing filter lets it approximate a sharper, more precisely defined frequency response, since more taps give the filter more coefficients to work with in shaping that response, answer B. A higher data rate, lower Q, and using double-precision math routines don't by themselves make a filter's response sharper the way increasing the tap count does.
