Given:
The angle modulated signal is given by
ϕm(t) = cos(ωct + 5 sin (1000πt) + 10 sin (2000πt))
instantaneous frequency
Where ϕt is the phase of angle modulated signal.
In the above expression

An angle modulated signal with carrier frequency refers to a type of signal where the frequency of the carrier wave is varied in accordance with the information being transmitted. This modulation technique is commonly used in frequency modulation (FM) and phase modulation (PM).
In FM, the frequency of the carrier wave is changed in proportion to the amplitude of the modulating signal. This means that as the amplitude of the modulating signal increases, the frequency of the carrier wave increases, and vice versa. This results in a signal that is resistant to noise and interference, making it ideal for applications such as radio broadcasting.
In PM, the phase of the carrier wave is changed in proportion to the amplitude of the modulating signal. This means that as the amplitude of the modulating signal increases, the phase of the carrier wave changes, and vice versa. PM is commonly used in applications where the phase information of the signal is important, such as in radar and telecommunications.
Both FM and PM are examples of angle modulation, where the phase or frequency of the carrier wave is modulated to carry the information being transmitted.
