Consider a pure Aloha network with an infinite number of nodes on a straight line of lengtha. Each packet transmission is of unit length, and transmissions are attempted according to a Poisson process of rate G. Assume that in this network there are only broadcasts and that a transmission should be received at all the nodes. A transmission is a success only if it is received correctly at all the nodes. a. Find the conditional probability that a transmission starting atx,0≤ x≤a, is successful. b. Find the broadcast throughput of the network.
Implement the following function with a 4-to-1-line multiplexer Draw the truth table and the corresponding block diagramfor the MUX F(x,y, z) = f(1, 2, 6,7)
Devise a system that will convert this temperature range into an 8-bit digital word with conversion from 00H to 01H at 200°C and from FEH to FFH at 350°C . An ADC is available with a 2.500-V internal reference. At 200°C a type K TC produces 8.13 m..
There are two four bit messages, 1010 and 1110. The first one is appended with an odd parity bit, the second one with an even parity bit. What are the values of the parity bits for the first and second messages respectively.
A filter has the following characteristics: Attenuation is 0 dB from 0 Hz to 2.5 kHz. Phase angle decreases linearly with increasing frequency above 2.5 kHz. Above 5 kHz the filter has steadily increasing attenuation.
Derive a minimal state table for an FSM that act as four bit parity generator. For every four bits that are observed on the input w during four consecutive clock cycles, the FSM generates the parity bit p = 1
Work out the following problem: If the analog signal to be quantized is a sinusoidal waveform, that is, x(t) = 6 sin (6283t), and if the bipolar quantizer uses 8 bits, determine 1. Number of quantization levels; 2. Step size of the quantizer ; 3. ..
A firm leases land from you for 15 years to build a warehouse. As payment you will own the building after 15 years estimated to be worth $400k however you must pay taxes and maintenance of $15k per year.
Let the component at Omega(C) = 2pi* 3000 be the corrupting signal. Design an appropriate lter to lter out this component of the input. You can use fir1 command for this. Plot the frequency response of this lter.
Design an AC source system that can be used to power 120 Vrms, 240 Vrms, and 208 Vrms single phase devices depending upon the particular connection terminals. The system should have no individual sources with voltages larger than 120 Vrms.
When you get to work one day you see that the station is delivering 6.0 MW of power with a power factor cosf=0.9. What is rms current. How much capacitance you should add in series to bring the power factor to 1.0. How much power the station will b..
A 120 V lamp-dimming circuit is controlled by a rheostat and protect from excessive current by a 2 A fuse. To what minimum resistance value can the rheostat be set without blowing the fuse
design a calander systen that will output the number of days in a month, when the number for a month is input, I need some direction on how to start this project. This needs to be designed using simple logic gates.
