Capacitance can be altered by immersing part of the two wire line into a different medium.
(a) What is the capaccitance per unit length in F/m of the transmission lines? You must explain your reasoning and show the equation you used.
(b) For a sanity check plug a=1 into your equations and compare the capacitance per unit length of case (a) to case (b), which is higher?
A balanced three-phase inductive load is supplied in steady state by a balanced three-phase voltage source with a phase voltage of 120 V rms. The load draws a total of 10 kW at a power factor of 0.85. Calculate the rms value of the phase currents
Design a class - A transformer-coupled emitter-follower amplifier to deliver 10 W to an 8 Ohm speaker. The ambient temp is 25 C and the maximum junction temp is Tj max = 150 C. assume the thermal resistance value are dev-case = 3.2 C/W
You have a bandwidth of 10 MHz (per direction) in a single-cell system and want to deploy a wireless telephone system. You have the following options: analog 30-kHz channels (as in AMPS)
Energy of a moving charge, A region in space has an Electric field given by E = x(x^) - y(y^) + xy(z^) where (x^), (y^), (z^) indicate corresponding letter with caret on top of it.
What is the resistivity of the wire? conductivity? Using the original dimensions of the wire, how much current can you pass through the wire until a 5V signal is degraded 5% or more?
1.)An op amp requires the design equation Vout = 5Vin & 2Vref + AgVg. What is the value of Ag 2.)The voltage dropout of a voltage regulator is 1.6 V. If a 16 V output is required, what is the minimum regulator input voltage
The U.S. Digital Cellular provider uses a TDMA scheme for multiple access. It uses a 48.6 kbps data rate and supports three users per frame. Each user occupies two of the six time slots per frame. Compute the raw data rate provided for each user.
Design channel coding performance simulator that compares two channel coding technique X and Y . You can provide pseudocode or block diagram of the simulator.
The system contains a door sensor, a window sensor, and a key activation switch. If the switch is on, opening the window will set off the alarm immediately. Opening the door will start a 30 second timer.
How are the left (L) and right (R) signals obtained separately in the radio receiver to drive the dual channel audio amplifier and speakers?
Build a series circuit consisting of a 130 V 60 Hz ac source, a 5 ohm resistor, a 53.05 mH inductor, and a 0.33156 mF capacitor. a) Draw the ac circuit diagram b) Sove for the phasor current and phasor voltages across each component.
