Q 1: A continuous-time system has a response that is the cube of its excitation. Classify the system as to linearity, time-invariance, BIRO stability, causality, and memory.
Q 2: A discrete-time system is described by: ny[n]-8y[n-1]=x[n]. Classify the system as to linearity, time-invariance, BIRO stability, causality and memory.
Q 3. Evaluate the convolution integral y(t) = x1/(t) * x2(t) using the graphical approach where x1(t) and x2(t) are given in the figure below.
Q4. Sketch the waveform of the convolution sum y[t] = x[n] * h[n], where
x[n] = n x (u[n] - u[n-5]) and h[n] = δ[n-1] - δ[n-3].
1. What should the length of an antenna be if it is going tobe used to send data at 145.01MHz, assume a 1/4λmonopole antenna is used. 2. The impedance of an antenna was measured as z = 17 -j470Ω what does this mean
What is specific application or product that might involve the z-transform and how is it relevant in the application or design of the application or porduct
A voltage source is in series with a 1 MΩ resistor and a100 picofarad capacitor. The voltage source is 10cos(2π*10^3t - π/6). What is the voltage across the capacitor
An initially uncharged 2 microfarad capacitor is connected in series with a 10 k-ohm resistor and a 12 V battery. Find the charge and voltage on the capacitor after a very long time and find the voltage and charge on the capacitor after one time co..
An Opamp has a low frequency gain of 10^5 and a high frequency response with a single pole at 100 rad/s and a pair of poles at10,000 rad/s. (a) At what frequency does the total phase shift reach 180 degrees.
Each single phase transformer has an identical number of turns in the primary and secondary windings. If a line-to-line voltage of 480V is applied on the wye windings, compute the line-to-line voltage on the delta windings.
What legal condition must be present for a Surety to act There are 6 courses of action that he can take (see slide 102). Assume the contract in question is to repave the Founder's Lot at UOIT; Pave-M-Good (PMG) being the contractor
The low-voltage winding of a transformer has 200 turns, and the high-voltage coil has 11,000 turns. The transformer is operated as a step-down transformer, and 13.2KVolts is impressed on the primary side.
