Question

A sinusoidal message signal having root mean square value of 4 V4\text{ V} and frequency of 1 kHz1\text{ kHz} is fed to a phase modulator with phase deviation constant 2 rad/volt2\text{ rad/volt}. If the carrier signal is c(t)=2cos(2π106t)c(t) = 2 \cos(2\pi 10^6 t), the maximum instantaneous frequency of the phase modulated signal (rounded off to one decimal place) is ________ Hz.
