- Find the transfer function for the circuit shown in the figure. Plot the amplitude graph of 2log10[H(jw)] and the phase angle graph of H(jw) Calculate the actual cutoff frequency? Calculate the true phase angle at the cutoff frequency?arrow_forwardDefine a truncated sinusoid function. Use fs=100 Hz for time 0 to 10. From time 0 to 5 define a sinusoid of frequency 1 Hz. After that the signal should be 0. Plot this. Compute the FFT of this signal using N points (N=length of signal) and plot the magnitude of the first 100 frequencies along with the correct frequencies (scale n/N by fs). Can you identify the primary frequency of your signal from this plot? Are there other frequencies and why or why not? Repeat this analysis using 10N points in the FFT (and plot 10x as many frequencies so you have the same range shown). What did this do to the DFT and to your resulting magnitudes.arrow_forwardsketch the double side Amplitude and phase Spectrum of the following signal.( NEED NEAT HANDWRITTEN SOLUTION ONLY OTHERWISE DOWNVOTE).arrow_forward
- 2) A voltage signal consists of the following periodical waveform: V(t) = 10 sin 502.7t + 5 sin 94.2t + 15 sin 942.5t where t is in seconds and Vin volts. This signal is sampled digitally at a sampling frequency of 200 Hz. 128 data points are taken. a) Recommend additional procedures to sample the signal properly in the frequency domain considering the sampling conditions given above. b) Sketch what the frequency spectrum would look like if you were to perform an FFT on these sampled data. Label your axes carefully. c) Calculate: - the total sampling time - the time increment between sampled data points - the frequency resolution of the frequency spectrum - the Nyquist frequencyarrow_forward1. Suppose you have multiple sinusoidal signal sources with four different frequencies where fj-4, f;=3, fz=2, f4=1 and their amplitudes Aj=A2=A3=A4=1. Together these signals form the message (modulating) signal (as shown in the figure below). Now, create a MATLAB program using built-in functions to generate the DSB Amplitude Modulated signal, and then recover the original signal (generate the Demodulated signal) from the modulated signals for time 0arrow_forward01 for the signal that is shown in the figure below A) plot the amplitude spectrum B) Determine the total power C) Find the value of (n) such that the power reaches %50 of the total powerarrow_forwardFor a series RLC circuit with a sinusoidal input voltage, the amplitude of the current passing through the circuit (lo in mA) is plotted as a function of frequency for two cases: Curve 1 with R1, L1, and Curve 2 with R2.
