We would like to modulate the message x(t) = sin(2000πt). For FM modulation take k=200000π and for PM modulation take k=8000π. a) Estimate the bandwith of FM modulated signal yFM(t) and PM modulated signal yPM(t). b) Repeat part (a) if the message signal amplitude is doubled. c) Repeat part(a) if the message signal frequency is doubled. d) Comment on the sensitivity of FM and PM bandwidths to the spectrum of x(t).
2. 12 pts] An FM system has a modulation index β-6 aid the input signal-to-noise ratio SNR 25dB. The message is a periodic square wave given in the figure below pulse width -0.2m 2 0 0 t (ms) a) What is the output SNR.? b) What is the proper value of the message bandwidth? [Justify your answer. c) What is the corresponding FM transmission bandwidth? d) If the modulation index is kept at β 6, what should be the increase...
Program Description: A C# app is to be created to produce Morse code. The Morse code assigns a series of dots and dashes to each letter of the alphabet, each digit, and a few special characters (such as period, comma, colon, and semicolon). In sound-oriented systems, the dot represents a short sound and the dash represents a long sound. Separation between words is indicated by a space, or, quite simply, the absence of a dot or dash. In a sound-oriented...
1. FM modulation. Consider a message signal m(t)-(2nt and a carrier wave c(t)-cos(400rt) (a) (20 points) Derive the FM modulated signal s(t) for ky-2 (b) (25 points) Find the Fourier transform, S(), of s(t) (Sketch to scale). (c) (5 points) What is the bandwidth of the modulated signal s(t).

a-Calculate the maximum frequency deviation for the FM signal v(t)= 5 cos(6000t+ 4sin2π.200t) b-What is the modulation index. Is it a NBFM or WBFM c-Calculate the transmission bandwidth by using Carson’s rule. d-What are the significant frequencies of the transmitted signal.
msp430 launchpad 2553 C programming Write a program for the microcontroller that flashes the Morse code pattern of a string. The Morse code is a system used to transmit characters and numbers through light or sound signals. Each character is mapped to a series of ‘dots’ and ‘dashes’ as shown below. For example, the letter A is (dot-dash), the letter B is (dash-dot-dot-dot) etc. To show a Morse letter on the microcontroller, the LED blinks for a short duration to...
