Design a full wave unregulated dc power supply having an input of 220 V rms 60 Hz and an output voltage maximum of 19.5 V and a minimum of 15 V. This power supply will be needed to provide power to a load which requires a maximum current of 500 mA. Assume the diode and transformer are ideal.a. Circuit Configurationb. Transformer winding ratioc. Capacitor size
The input impedance of a 31cm long lossless transmission line of unknown characteristic impedance was measured at 1 MHz. With the line terminated in a short circuit, the measurement yielded an input impedance equivalent
Create a complete C++ program that prompts the user to enter his or her height in inches and outputs the following: Output "Height is six feet or more." when the user's height is 6 feet or more. Output "Height is less than five feet."
Consider an angle-modulated signal xc(t) = 10 cos{(10^8)pi t + 5sin 2pi(10^3)t}. Find the maximum phase deviation. Find the maximum frequency deviation.
A cylindrical conductor of inner radius a and outer radius b carries a steady current, I. The current density in the conductor is uniform. Find -B (magnetic flux density) as a function of (rho) , the distance from the axis of symmetry of the conduc..
For a 64-PSK modulator with an input data rate(fb) equal to 36 Mbps and a carrier frequency of 100 MHz. A. Determine the minimum double-sided Nyquist bandwidth(fN) and the baud. B. Sketch the output spectrum.
The counter should be designed using D flip-flops and using the state equation method. (No credit will be given if the circuit is designed using the excitation table method.) Draw the final logic diagram.
Develop the pseudo-code below for a program that will retrieve 2 bytes (NUM1 and NUM2) from memory, determine which is closest to the numeric value 50, and indicate the result by setting a variable named "CLOSEST" to 1 (if 1st byte is closest) or ..
The R2= 6 homs load in the circuit is absorbing four times as much average power as the R1 = 20 ohmsohms load. The two loads are matched to the sinusoidal source that has an internal impedance of 500 (angle) 0 1)What is the numerical value of a1
You are designing a 2.4 GHz receiver with a 140 MHz IF. System design constraints require that the local oscillator power be minimized to reduce the potential for interference to other systems as well as to reduce the receiver power consumption.
A thermometer, initially at a temperature of 75 degrees Fahrenheit is suddenly immersed into a tank of water with a temperature of 180 degrees Fahrenheit. The time constant of the thermometer is 4 s.
The purchaser of the motors is guaranteed the option of returning the defectives for repair. If the repair cost is given by 3Y^2 + Y + 2, find the expected repair cost the warehouse owner must be prepared to pay.
A three-phase wye-delta transformer is rated 225-kV:24-kV, 400 MVA and has a single-phase equivalent series reactance of 6.08 ohms as referred to its high-voltage terminals. The transformer is supplying a load of 375 MVA
