Write a program that accepts a date from the user in the form mm/dd/yyyy and then displays it in the form month dd, yyyy, where month is the written name of the month. Store the month names in an array that contains pointers to strings.
An additional motor load of 100 kW is needed. Find the new kilovoltampere load and power factor of the plant load if the motor to be added is (a) an induction motor with a power factor of 90 percent lagging, and (b) an 80 percent leading power fac..
The sampling frequency in a DSP system is fs=8 kHz. Anti-aliasing filter used in the system is the second-order Butterworth filter with cutoff frequency of fc=3.4 kHz. What is the percentage of aliasing level at the frequency f=2.5 kHz
Describe the charge diffusion and drift in a PN junction, without and then with an applied voltage
Seawater with a specific weight of 64.0 lbs/ft^3 is at a level of 4 feet above the centerline of the exit pipe. The tank is closed at the top and there is a pressure of 1 psig above the seawater. What is the velocity at the end of the pipe
A 1 kHz sine wave signal with a power level -10 dBm is applied to the input of the amplifier. What is the power at the amplifier output?
Find the Laplace transform of a rectangular voltage pulse that is 0 V until time 0 s, then jumps to 5 V and stays there until time 2 ms, then returns to 0 V and stays there after time 2 ms. Hint: express the pulse in terms of unit step functions.
a radio antenna operating at 1.5 MHz has an input impedance of 6+j226 ohms. A capacitor is connected in series with it for tunning purposes. compute the valur of capacitance needed to tune the antenna to resonance.
mesh analysis involves writing and solving a number of simultaneous equations. The number of equations is equal to the number of independent loops in the circuit. Each equation is derived from the application of KVL around the loop.
