Write an asm HCS12 program to flash LEDs on a dragon+ board three times when SW5 is pressed with a 5 kHz frequency, and 50% duty cycle clock signal. Generate a clock signal with 5 kHz frequency, and 50% duty cycle. Flash LEDs (PB0-PB7) three times at frequency 1 Hz based on the generated 5 kHz signal.
A three phase, 25-hp, 440-V, 60-Hz, 1750 rpm, wound-rotor induction motor has the following equivalent circuit parameters:R1=0.20 ohms, X1=1.0 ohms, R2=0.15 ohms, X2=0.8 ohms, Xm=30 ohms The motor is connected to a three phase, 440-V, 60-Hz supply.
What is the problem you are investigating and explain the issue, its history, the impact it makes locally
Finding the periodicity in N of the discrete time signal x(n) = Cos(3pi*Ts.n + pi/4) and then plotting the discrete signal. From this the condition on the sampling period is determined
Calculate the percentage second harmonic distortion present in the output. Calculate the percentage error in the output voltage compared to its ideal value at the instant of time when t= 1/3200 seconds.
Find the applied voltage of an iron-core transformer if the secondary voltage is 240 v, and Np = 60 with Ns = 720
Suppose that we wished to match an admittance using a double-stub tuner where the stubs are lambda/4 apart. For what range of admittance values can
