The system with frequency response H(\\omega)=(10)/(3+j\\omega) to x(t)=10cos(4t+(\\pi)/(4)) is: y(t)=10cos(3t+(\\pi)/(4)+tan^(-1)((3)...

What is the system's frequency response to x(t)?
A) H(\\omega)=(10)/(3+j\\omega)
B) H(\\omega)=(3+j\\omega)/(10)
C) H(\\omega)=(10)/(3-j\\omega)
D) H(\\omega)=(3-j\\omega)/(10)
