The system described in MATLAB is frequency selective. Replace the random binary input in this example with an input of the form
And show via simulation that the two input tones are affected differently by the time-varying system, thus demonstrating the frequency-selective nature of the system.
For the Circuit shown below, V1=5V, R1= 20 kiloOhm, R2= 100kiloOhm, and C= 0.1 microF. Assume the switch in the circuit below has been open for a long time. At t=0, the switch is closed and at t=5 sec the switch is re-opened.
Suppose there is only a single user (i.e., K = 1). From your plot in part (1), do you think the dual transmit antennas provide any gain? Justify your answer. Hint: Use Jensen's inequality.
When communicating with a geostationery satellite from earth,the distance between transmitter and receiver is approximately 35000km.assume that the friis law for free space loss is applicable and the stations have parabolic antennas
A positive sequence three phase source has Van(t)= 200cos(wt+120) V. Find time domain expressions for vbn(t), Vcn(t), Vab(t), Vbc(t), and Vca(t).
The preceding example demonstrated the required amplitude response of the VSB filter. We now consider the phase response.
Write a MATLAB function that will perform a single interpolation given five numbers are input arguments and return the interpolated values as the only function output. Write a MATLAB program that will calculate the following scenarios.
Suppose the voltage divider circuit P3.19(a) is connected to the voltage divider shown in circuit P3.19(b), i.e., a is connected to a' and b is connected to b'. Find vo.
Design a UV flip-flop using a JK flip-flop and two logic gates. where the characteristic table for the UV flip flop is U V Q(t+1) 0 0 1 0 1 !Q(t) 1 0 Q(t) 1 1 Q(t)
Display the elapsed time in the LCD display (or seven-segment displays) and stop the time display when a player wins the game (turns out all LEDs). Adjust the shift time delay for reasonable game play. Blink all of the LEDs when a player wins. If ..
2. What is the expected output frequency of a sample and hold system if fs= finput 3. Which is input frequencies will give an output frequency of 50 Hz when put through a sample and hold system if our sampling frequency is 488 Hz
A circuit consist of two impedance,Z1=50/_45 ohms and Z2=25/_30 ohms, connected in parallel. They are supplied by a source whose voltage is V=50/_0 volts. Determined follows 1. the current drwan by each impedance
What idea leads to the digital signal which filters directly in the time domain and thus avoids transformation into the frequency domain and back again my means of the FFT?
