A star network with a hub, and 3 nodes:Transmission rate R=10Mbps, Frame length L=1000 bits, Cabledistances from the hub to the nodes are d1=d2=100 meters,d3=200meters.Propagation speed is the speed of light.(a) Derive E in terms of bit-time.(b) What is E when R=100Mbps? 10Gbps? How does Evary with R?(c) When the network has an equivalent bustopology, what is E?
The voltage across the load must remain between 4.7 and 5.0 V for all values of load current. Design a voltage-divider network to supply the load. You may assume that resistors of any value desired are available.
b) What are the equilibrium electron and hole concentrations at 300K and 500K (hint: You will have to find Nc and Nv at 500K, but it isnt necessary for 300K) c) Why does the mobile carrier concentration increase at high temperatures
The impurity is removed with practically no loss of carrier liquid. By local ordinance, a maximum of 100 ppm is allowed in the discharge to a nearby river. The treating process removes all but 10 ppm.
Obtain a minimized equation for the function F(X,Y,Z)=Σ(0,1,3) + Σmd(5,6,7) then draw a schematic to implement the minimized function in SOP form using AND, OR and inverters. Draw a schematic implementing the function using only NOR and inverters.
Design a second-order band-pass filter for a system with sampling frequency of 18 kHz that is tuned for f=5kHZ The filter should not have any sample delay (the numerator and denominator orders are equal) and should have a stability margin of 92%.
Design a continuous time system to generate output y(t)=sin(wt)u(t) when the input is a unit step function. Specify the system using a differential equation.
Given a parallel resonant circuit with the following components: a 10mA source with a zero degree phase angle in parallel with a 10k ohm source resistance, a parallel inductor of 80uH with an internal resistance of 1.5 ohms
Rain harvesting is a means of water conservation. This real-life problem requires computation and critical thinking involving a practical solution. Apply the problem solving approach studied in class to this rain harvesting and irrigation problem.
Consider a superheterodyne FM receiver designed to receive the frequency band of 88 to 108MHz with IF frequency 10.7MHz. The range of frequencies generated by the local oscillator for this receiver is 77.3 to 118.7 MHz.
1.) (a) What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers. (b) What is the advantage of using the 2's-complement system to represent signed numbers.
A simple voltmeter with a full-scale reading of 50(V) is required. Use a d'Arsonval movement with a rating of 20(mV) at 1 (mA). Calculate the value of the voltmeter resistor, Rv, required to achieve these design specifications.
A transconductance amplifier with Ri = 2 kΩ, Gm = 40 mA/V , and Ro = 20kΩ is fed with a voltage source having a source resistance of 2kΩ and is loaded with a 1kΩ resistance. Find the voltage gain realized (from the source internal voltage to the o..
