The far-field pattern of an antenna can be modeled as the twodimensional Fourier Transform of the aperture.Determine the 2D FourierTransform for the function.This will require two transformations from rectangularcoordinates, one in the spatial domain and one in the frequency domain. There are two key transformations. Explain.Hint: This problem involves Bessel functions of the first kindof orders zero and one.
When unmodulated the carrier voltage is 75 volts peak. An information (modulating) signal of 15 KHZ with 5 volts peak amplitude causes a frequency deviation of 22.5 KHz. If the load resistor RL= 100 Ohms, determine the following Modulation index
