Consider the 2x2 3-db coupler and suppose we connect the two outputs with a piece of fiber. Assume that the polarization are preserved through the device?
a 20 mH inductor with an internal resistance of 20 ohms is connected in series with a capacitor and a voltage source with a thevenin resistance of 60 ohms. a. what value of C will be needed to produce Wo = 6 krad/s
Open Neutral Assume that the load is star connected with the neutral disconnected. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Plot the neutral voltage Plot the phase to neutral voltage for phase a.
A class C amplifier severely distorts the signal. How can we use a resonant tuned filter to get the desired signal at the output What type of transistor (BJT or FET) would you like to use at the front end (first amplifier) of a receiver
The circuit is also required to recognize overlapping sequence such that if the input string is x = 1101111111010 then the output will be z = 0000001111000. Use D Flip-Flops AND a separate design with JK Flip-Flops.
Electric vehicle supercapacitor. a. A 3000 F capacitor has initial voltage 200 V. If the capacitor is discharged at a constant 60 A, what is the voltage across the capacitor during discharge. b. How long will it take the capacitor to discharge to 5..
A 300 ohm feedline is to beconnected to a 5-m long, 200 ohm line terminated in a 150 ohmantenna resistor. Both lines are lossless and use air as aninsulating material, and the operating frequency is 30MHz.
The bandwidth of interest is between 0.5 and 50 Hz and has peak amplitude of approximately +/-1 mV. -a. Design and draw a block diagram (not circuit) of the signal conditioning portions (everything before ADC) of your system.
An absolute encoder is to be used for measurements that require a minimum resolution of 0.05 minute or arc. What is the number of bits required to achieve the specified resolution
Design an two or three stage amplifier that :Operates from single supply of no more than +10 V, and consumes no more than 10 mA. Has an RIn = 50 Ohms w/in 10%. Has an ROut less than or equal to 1kOhms.
2 single-phase AC motors connected in parallel are fed from a220 volt source. The motors have the following ratings: Motor #1: 220V, POUT = 50 hp, Efficiency = 82%, PF =0.82 lagging Motor #2: 220V, POUT = 75 hp, Efficiency = 86%, PF =0.85 lagging
