Concept explainers

Frequency Modulation

Frequency modulation is a method or process of encoding the data of a specific signal (analog or digital) by modulating the carrier wave frequency according to the frequency of the modulated signal. Modulated signals are nothing more than information or data that should be conveyed after being converted into electronic signals.

Question

Design a wideband FM transmitter to achieve an output carrier frequency of
fo= 1.7 GHz, and an output frequency deviation of Afo = 15 kHz using
heterodyning, frequency multiplication, and bandpass filter operations. At the
front-end of the transmitter you have a narrowband FM modulator with a carrier
frequency of fe = 85 MHz, and a frequency deviation of Afi= 150 Hz. The
input message waveform has a bandwidth of W = 15 kHz. For this system
specifications:
1. For each stage of the design tabulate the 3, carrier frequency, frequency
deviation, and Carson bandwidth of the corresponding waveform
2. Specify the center-frequencies and the bandwidths of the BPF's involved.
3. Determine the implementation of the frequency multiplication and het-
erodyning operations, specifying the components involved and the block
diagram for each component.
