Problem 7.2 Consider the signal x(t) = sinc(6t) sinc(4t). (a) Sketch the spectrum Ŷ (ƒ). (b) Consider the impulse train sampled signal xs(t) = Σ x(nT)&(t - nT) n=-∞ where T = ½. Sketch the spectrum of Ŷs(f). (c) The sampled signal x,(t) is passed through an LPF HLPF(ƒ) = (f) to obtain the signal x,(t). Sketch the spectrum Ŷ, (ƒ) and give an explicit expression for the time domain signal x(t). Is it the same as the original signal x(t) (up to scale)? (d) Repeat (b) and (c) for T = 1 12° (e) What is the maximum value of T for which x(t) = x(t) (up to scale)?

Example: If the analog signal to be quantized is a sinusoidal waveform, that is x(t) = Asin(2 x 103nt) and if the bipolar quantizer uses m bits, determine the SNR in term %3D of m bits

Given the continuous-time, continuous-amplitude signal waveform x(1) -3 sample at discrete values of time and plot the discrete-time signal x[n]. Also, extract the even and odd parts of x[n]. Please show the complete and detailed solution. Thank you

Thanks

please have step by step solution and explain along the way. also please no chatgpt or some sort it is always wrong

Consider the continuous-time signal: x(t) = e^(j9t) + 6je^(j6t) "A" is an exponent symbol. Fundamental period of the signal is Fundamental frequency of the signal is TTS rad/s

Given responses in a first-order RC or RL circuit, (a) describe how you would find the circuit parameters or other responses. (b) How would you find the circuit’s natural frequencies and initial conditions (if not given)?

Please I need a complete solution. Thanks!

Problem 2 Each of the following figures shows the impulse response of a LTI system h[n]. For each figure in (a), (b), (c) and (d): (i) Firstly write an expression of h[n] and then find an expression of the frequency response of the system: h[n]e-inw (ii) say whether H(e) as a function of w is even or odd or neither (iii) and sketch/plot the magnitude of the frequency response, i.e., H(ew)|, over -27 < w 2π (you may use Matlab). (a) (b) In each figure, the value indicated for each impulse means the amplitude of that impulse. For example, if the value of an impulse at n = 3 is indicated to be 2j, it means 2jd[n – 3]. The value of h[n] is zero for all n outside the range shown in the figure. h[n] (c) H(ejw) = h[n] 1 1 1 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 h[n] -6 -5 -4 -3 -2 -1 0 1 -6-5-4-3-2-1 0 1 n=-∞ 1 1 1 1 1 2 3 4 5 6 2 3 4 5 6 n n h[n] is real-valued. h[n] is real-valued. h[n] is real-valued.
