The number of turns in primary and secondary of an ideal transformer are N1 = 50 turns and N2 = 400 turns. The primary winding is connected to a 120 - V, 60 Hz source with a source resistance of 50 Ω. The secondary winding is connected to a 1600 -Ω load. Find the primary and secondary currents.
The pre- Limiter circuitry has a Noise Figure of 8dB and an input Noise Temperature of 1800C. Given an FM demodulation noise improvement of 17dB, determine the minimum receive signal power to achieve a post detection signal to noise ratio of 35dB.
How could the rising-tone acoustical illusion be modified to obtain a tone that goes up and down in pitch at the same time.
Design a counter that will execute the numerical sequence 0, 2, 4, 6,repetitively. Unwanted states should be directed into wanted states that give the simplest logic functions. - Identify the number of required JK D-FLIP FLOP;
a capacitor, an electric resistance heater, and an impedance are connected in parallel to a 120 volt, 60 Hz. system. the capacitor draws 50 VARs, the heater draws 100 watts and the impedance coils draws 269 VA at a power factor of 0.74 lagging.
A company has 100 metal halides (400W each with 1.2 ballast factor) and four motors (each with 50 hp capacity, 95% efficiency, 100% load factor, and 80% power factor). The power factor for the combined load
a. Functionally, how do closed-loop systems differ from open-loop system b. State one condition under which the error signal of a feedback control system would not be the difference between the input and the output.
Use the upstream wind power relation to calculate the power in a 5-mph wind if the circular wind swept area has a diameter of 2 meters, and the elevation (altitude) is that of Logan, Utah. [Reference: Google: Images for air density vs. altitude]
pecify the value for R. What is the diode current with the load connected What is the increase resulting in the output votage when the load is disconnected What change results if the load resistance is reduced to 100ohms? To 75ohms To 50ohms
For a circuit with resistor of 10 K ohm and a capacitor of 5 micro Farads, what is the time constant in second?
Perform experiments using your circuit design. Using your digital scope, plot (and submit) input voltage and output voltage from your circuit design. Try to vary the filter portion (R, L, C) of your circuit and plot (and submit) output voltages.
AC source Voltage in series with R1(4 ohm) and then R2(1 ohm). Vs=9sin(2t +13degrees) find the instantaneous power deliverd to R2 (1ohm) at t=0,t=1,t=2
Assuming that the maximum depth of Kraken Mare is less than 400 meters, how much pressure in atmospheres must the submersible be designed to withstand Assumer the surface pressure on Titan is 17 kilopascals, the surface temperature is 94 kelvin
