(a) Using Convolution, find output y for input x = 8(n] + 28 +Ĩ and h(n] = U(n]. Let the discrete system is defined by input x, output y and system (c) Decide its frequency response H(elo). (b) Is this system stable? give reasoning for your answer. (a) Decide its system impulse response h(n). Compute the DC Bias (only IE).ĭraw the small signal model and find the overall voltage gains (vo/vsig). The Smith chart is actually a polar plot of the complex reflection coefficient (z) ratio of the reflected wave voltage to the forward wave voltage. Use the attached Smith Chart to find:(a)(2 points) The magnitude I and phase A of the reflection coefficient. Consider the lossless transmission line given below. (50 points) This problem has 14 questions.Find the input impedance Rin as indicated in the figure.įind the output impedance Rout as indicated in the figure. The Smith chart is usually normalized to a terminating impedance Z0 ( real). The circuit parameters are VDD=5V, Rs=1KΩ, RD= 4KΩ, R1=225KΩ, and R2=175KΩ.įind the circuit quiescent values IDQ and VDSQ.įindthesmallsignalvoltagegainforRLasanopencircuit. The VSWR is defined as the ratio of maximum to minimum measured voltage. An NMOS common-source amplifier circuit shown as the figure, the transistor parameters are: VTN=0.8V, Kn = 1mA/V2, and the channel modulation effect is ignored. how to solve any problem on translational mechanical system transfer function.(h) (4 points) Using I and din from previous questions, find the minimum voltage in terms Using I and dmax from previous questions, find the maximum voltage in terms of Vö (b) (2 points) Determine the Standing Wave Ratio (SWR).(c) find the normalized load admittance y and load admittance (d) find the normalized load impedance Zion and the load impedance Zion (e) what is the distance dmin from the load to first voltage minimum indicate on the smith chart the position of voltage minimum.(f) what is the distance dmax from the load to first voltage maximum indicate on the smith chart the position of voltage maximum (g) (4 points) The total voltage on a transmission line is given by: V (2) = Vat e-iP2 + Vi eiBE Views: 10 (50 points) This problem has 14 questions.
