2. Frequency Division Multiplexing (FDM), how does it work? Please draw diagram for illustration.

Why is the FM modulation index important?

A carrier signal is amplitude modulated by a sinewave. The resulting AM waveform is shown below. 3.5V- 1V- a) What is the amplitude of the carrier signal? b) c) To achieve 75 percent modulation, what amplitude of the modulating signal is needed? d) Calculate the effective voltage of the AM signal What is the modulation index?

I need the answer quickly

For a FM system, the maximum freq deviation is 75 kHz and the maximum freq of the info. signal is 10 kHz. What will be the total bandwidth of the FM system? What will be the modulation index?

Problem 2)- The figure below shows the binary input data and carrier signal that used in a optical comm system. Determine the data rate and baud rate for the following modulation schemes: a) Binary Phase Shift Keying b) Binary Frequency shift Keying. Assume the carrier swing is 3MHz. Input data Carrier 9 1 ' Sus Sus

Why is a high percentage of modulation desirable?

please answer with detail solutions with formula

Choose the correct answer low HDOP (Horizontal Dilution of Precision) number such as2 indicates a ........................... a.poor fix b.good fix c.poor signal quality d. good signal quality

What is the main advantage of using pulse-width modulation ( PWM) in power electronics applications?a) Higher efficiencyb) Lower costc) Simpler circuit design d) Reduced electromagnetic interference ( EMI) don't solve otherwise 10 dislikes
