- Please convert these values into time domain forms, not the rectangular coordinates, ie v(t) = Acos(wt + theta) formarrow_forwardDerive F{sin ω0t}.arrow_forwardDraw the following signal in time and frequency domains, respectively. S(t) = 5 sin (2π ft + θ) +3 sin (2π 2ft + θ) + sin (2π 3ft + θ) with f=2; θ=3π/2arrow_forward
- Solve the Fourier Transform of the following signals. complete solution. Box final answerarrow_forwardQuestion 1 Evaluate the area under sinx/x between -inf and +inf (use known Fourier transform pairs, not integration) Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line.arrow_forwardSketch the continous time signal u(2t+3)arrow_forward
- Applying Parseval’’s Theorem The current in a 40 Ω resistor is i=20e-2tu(t) A. What percentage of the total energy dissipated in the resistor is associatedwith the frequency band 0≤ω≤23 rad/s?arrow_forwardDetermine the fundamental frequency of the given continous-time signal, x(t) in Hz, and then express x(t) in terms of harmonic frequencies of the fundamental frequency. x(t) = sin((5pi/6)t - (pi/3)) + 2cos(3pi/4 t) - 3sin((pi/3)t + (pi/6)) Please show workarrow_forwardUnderstand Parseval’’s theorem and be able to use it The voltage across a 50 Ω resistor is v=4te-tu(t) V. What percentage of the total energy dissipated in the resistor can beassociated with the frequency band 0≤ω≤3 rad/s?arrow_forward
- For each of the following signals:a) x(t)=4 Cos(5πt)b) x(t)= 4 Cos (5πt-π/4)c) x[n]= 4 cos(πn-2)d) x[n]= 2 sin(3n)Analytically, determine whether these signals are periodic (if periodic, state theperiod) or non- periodic and also sketch the signals.arrow_forwardDefine periodic & non-periodic signal. Show whether the following signals areperiodic or not by basic principle.(i) A sin(ωt),(ii) (ii)e−at (a > 0) &(iii) x t =cos t ;t < 0sin t ;t ≥ 0arrow_forwardFind which of the following signals are periodic and find their fundamental period c) x[n]=cos(πn/2)- sin(πn/8)+3cos(πn/4+π/3)arrow_forward
