min/max delay filters

Hello,

This is help for a homework question, and I would not like someone to do
it for me, just help point me in the right direction.

The question is:
Consider the two-element filter [1.0 0.6]. Construct a finely spaced
dimensionless
frequency vector that extends from -1 to 1. Calculate and plot the
amplitude and phase lag
spectra for the filter. Identify the Nyquist frequency on the plots.

My thoughts are to use the freqz function, and set

A = 1
B = [1.0 0.6]
f = [-1:1/500:1]
fs = 500

And then run freqz(B,A,f,fs)

the plots just dont look right to me though.

does anyone see where I am going wrong? I know with filters there are
other things I could run (filter, fir, iir) but I am having trouble knowing
when one is appropriate.

thanks!

erin
