A sinusoidal signal g(t), with an amplitude of 3.25 volts, is sampled at 100 samples each period,...
2) An analog video signal with a bandwidth of 5 MHz. is sampled at one and half times the Nyquist rate. The signal is then quantized using a uniform quantizer. The resulting output is then sent over a channel with a bandwidth of 94 MHz. using binary PAM with a raised cosine pulse with a roll-off factor of α = 0.25 a) Find the maximum number of quantiozation levels possible (2 Marks) b) Find the resulting Signal-to-Quantization-Noise Ratio (make any...
Problem 2 (Spectrum of a rectangular signal): In this problem, the amplitude spectrum of the signal 1 or Ot 2 ms x(t)- 0 otherwise is to be analysed (b) Numerical calculation of the spectrum: (i) Use Matlab to generate and plot a vector containing the sample values of the rectangular signal defined in (2) sampled at f 8kHz. Choose the number N of sample values so that it is a power of 2 and that the signal duration is at...
Problem 31: (34 points) 1. (10 points) A pulse width modulated (PWM) signal fPwM(t) in Figure 2. The symbol D represents a duty cycle, a number between zero and one. Determine the compact trigonometric Fourier series coefficients (Co C,11 %) of the signal f(t). 2. (10 points) One use of PWM is to generate variable DC voltages. While the PWM signal is not DC, you should be able to see from your results in part 1 that it hss a...
This is taken from Section 4.6, "Amplitude Modulation and the Continuous-Time Fourier Transform," in the course text Computer Explorations in signals and systems by Buck, Daniel, Singer, 2nd Edition. I need the answers for the basic and intermediate questions. 4.6 Amplitude Modulation and the Continuous-Time Fouriei Transform This exercise will explore amplitude modulation of Morse code messages. A simple ampli tude modulation system can be described by x(t) = m(t) cos(Crfot), (4.13) where m(t) is called the message waveform and...
Vout should be a sinusoid signal of 12Vp-p Dc voltage to uA741 : +/-8.5V Please simulate as well please help, im completely lost on this this is all of the information Experiment 5. RC Sinusoidal Oscillators PURPOSE: This laboratory provides an introduction to the background, analysis and design of sinusoidal oscillators using RC feedback networks and active devices to achieve the criteria for continuous oscillations to occur. EQUIPMENT REQUIRED : 1 Operational amplifier u.A741 1 CEU development station Resistors and...
