(a) In Matlab generate a sine wave at 250 Hz and 10 kHz. Sum the signals...
In MATLAB, generate a square wave of period 1s and length of 8s, sampled at 1024HZ. The maximum value of the wave is 1 and the minimum value is -1. Take the fft of this data. Show both plots. The fft should represent Fourier series representation of the wave in lecture, comment on this aspect. Comment on the difference in FFT when I sample for 8.01 sec instead of 8 sec.
(A.) Use MATLAB to generate a pulsed sine wave signal having a frequency F-10KHZ and a pulse width of T-.5ms. The pulse repetition time is 1ms (pulse repetition rate is 1000 pulses/sec), i.e., the signal is zero between pulses. Model the signal to start at time t-0 and to end at a time t=Tstop. Use a sample time of .001ms to approximate an analog environment. Display the signal in MATLAB appropriate for an analog signal, first for Tstop 1ms and...
Using Matlab. I need the matlab code for: a. Plot a 1 Hz sine wave b. Plot the unit rectangle function. c. Plot the unit triangle function Show each over a plotting interval -5 sec to 5 sec.
Please answer this question using Matlab: Write a matlab function to generate and plot a sine wave at a specified frequency having at least 10 cycles, for this case the amplitude will represent voltage. Your sine wave should have a positive going zero crossing at T=0. Make sure your plot has at least 25 samples per cycle. Make sure the plot is with respect to time. Your function needs to return your generated samples and time vector. The frequency will...
Please can you solve it using MATLAB. (1) Generate random signals [n] and hn, each of length N, and measure the time it takes to compute the linear convolution of r[n using the linear convolution definition and using the FFT method . Plot a graph of the results for N 104 to 10 in steps of 10. (2) Consider the signal x[n]-cos(0.3n),。£11S 100. Generate a plot of: ·The magnitude and phase of the DTFT of x[n] for 0 2π The...

Design a digital sine wave oscillator with f= 440 Hz, Sample rate = 5 kHz. Can the amplitude be adjusted without multiplication?
assume we have converted an analog sine wave signal of frequancy equals to 250 hz and amplitude equals to 4 volts into a PCM digital signal of zeros and ones . consider that one period of the anloge sine wave can be represented by 18 samples after sampling process ,whereas the number of quantization level is 32 show all the drawing and calculate the and calculate the time duration of the analog sine wave signal
