Signal Sampling Problem Hi! Good morning, can someone help me to solve this following sampling excercise? A digital communication link carries binary-coded words representing samples of an input signal Xa (t) = 3 cos 600πT + 2 cos 1800 πT The link is operated at 10000 bits/s and each input sample is quantized into 1024 different voltage levels. What is the sampling frequency and the folding frequency? What is the Nyquist rate for the signal Xa (t)? What are the...

Hi, if someone know just the half of the answer it's ok i real need help in this one , it is the 3 rd times i post it and no one answer me :( Probleme 1: A cellular phone operates in two modes: an analog mode in the band frequencies of 900 MHz and a digital mode operating in the frequency band 1900 MHz. The cell phone uses a superheterodyne receiver with an intermediate frequency, fIF = 500 MHz,...
can someone help me do this and maybe also the picture of the
scope explain how you get it. thankyou!
Frequency-shift keying (FSK) and Phase-shift keying (PSK) Two other modulation schemes are the phase-shift keying (PSK) and the frequency-shift keying (FSK). These are illustrated in Figure 8 b and c respectively. In phase-shift keying the carrier signal changes phase by a radians when the digital signal changes values. In frequency-shift keying a 0 is transmitted at a different carrier frequency...
1. An A/D converter will convert voltages over a 0 to 10 V range. How many bits must it be to achieve a 1 mV resolution over the entire range? 2. You have an A/D converter that will convert over a range of 0 to 5 V. You input an analog signal to it that has a range of 1 to 3.5 V. What must be the number of bits of the converter to achieve a resolution of 1% of...

Can someone help me with this questions. Thank you! 1.) Answer the follwing on Hooke's law. a) What are the dimensions (units) of a spring’s force? b) What are the dimensions (units) of the spring constant (also called the force constant)? c) What is the natural frequency of oscillation of a 94.9 g mass attached to a spring with a force constant of 23.6 N/m?
PLEASE HELP ME ANSWER THE QUESTIONS TO THIS EXPERIMENT!! It's very important to answer and EXPLAIN the question to part b) !!! The DFT of a Rectangular Window & The Effects of Zero Padding a Signal a) Plot the 4-point magnitude DFT of the following pulse w[n] = [1 1 1 1]= [w[0] w[1] w[2] w[3]] (Use the FFT command in MATLAB.) b) Conveniently zero pad the signal in order to plot the 8-point DFT, the 16-point DFT and the...
