USING MATLAB TO COMPUTE MAGNITUDE AND PHASE INFORMATION

MATLAB commands required to display magnitude

and phase as function of frequency

NOTE: Instead of comma (,) one can use space to

separate numbers in the array

EXAMPLE

» num=[15*2.53*1e-3,0];

» den=[0.1*2.53*1e-3,15*2.53*1e-3,1];

» freqs(num,den)

Missing coefficients must

be entered as zeros

» num=[15*2.53*1e-3 0];

» den=[0.1*2.53*1e-3 15*2.53*1e-3 1];

» freqs(num,den)

This sequence will also

work. Must be careful not

to insert blanks elsewhere
