Bandwidth of cosine of bandlimited signal
I have a signal $x(t)$ with bandwidth $B_x$, and I am taking its cosine to create $y(t) = cos(x(t))$. After checking the spectrum with FFT, it seems that $y(t)$ is also bandlimited. … If so, what is the bandwidth? …

Is my solution correct?
You basically have a rectangular wave with frequency $f = 15$, amplitude $A = 2$ and duty cycle $D = 15/25$.
Let me start from the end. To write the series as real-valued trigonometric functions, you …
