Need MATLAB plot code.

1. Design FIR filter with cutoff at 0.6 (Low Pass filter). Stem plot in length 15 coefficient.

( need magnitude plot of frequence response, and magnitude dB plot of frequence response) x-axis 0:1

2. Design High Pass filter with cut off at 0.4 length 60 coefficient.

(plot stem of coefficient, and dB magnitude of frequence)
