Hi all,
I have an equation of the form:
\(y(t) = 5\cos(\omega t) + \frac{5}{2}(1 + \cos(2\omega t))\)
and I have to plot the power lines
\(
P_0(\text{dBW}) = G(\text{dB}) + P_i(\text{dBm})\\
P_2(\text{dBW}) = G_2(\text{dB}) + 2 P_i(\text{dBm})\\
\)
in dBW scale using loglog function as it's requested by an exercise and I am quiet confused how to use it.
I started using this code:
but of course it's not what I am looking for since I should obtain something like this plot
Do you have any suggestion about how accomplish this ?
Thank you.

Code:
t = linspace(-10, 10, 10000);
f0 = cos(2*pi*t);
f1 = 5*f0;
f2 = 4*f0.^2;
f = figure();
loglog(f1); hold on; grid on; loglog(f2);
waitfor(f);Do you have any suggestion about how accomplish this ?
Thank you.
