In angle modulation, signal to noise ratio before detection is a function of ______

In angle modulation, signal to noise ratio before detection is a function of ______ Correct Answer IF filter bandwidth

In angle modulation systems, the signal to noise ratio before detection is the function of the receiver IF filter bandwidth, received carrier power, and received interference. However, signal to noise ratio after detection is a function of maximum frequency of the message, input signal to noise ratio and modulation index.
