Vasco da Gama is a famous explorer from Sines‚portugal. His date of birth isn’t confirmed but it is guessed that he was born around 1460. Vasco was born in a wealthy family with power ‚ so from the start he had a great opportunity to become great. Being from a wealthy family with great connections he was able to get an excellent education. He became extremely talented when it came to math and navigating. Vasco joined the navy as soon as he could the skills that he learned from school made him very

Around my city I see communities devasted be opioid overdoses. It is very devastating to see stories about overdoses on the new‚ in newspapers‚ and online. People should be able to treat their pain without worrying if they will get addicting or even dying. It is important that we recognized these issues while they are still new. I know a few

#5 Calculations #6 Graphs #7 Questions & answers #8 Conclusion Objective In experiment 2 our main objective was to understand the analysis of resistors‚ inductors and capacitors in a sine wave circuit. we measured the impedance of the inductor and capacitor using a current sensing resistor. Inductive reactance is the opposition to the flow of current‚ and capacitive reactance is the opposition to the flow of charge. The tools we used

measured in watts‚ while VIr is the reactive power‚ measured in vars (volt-amps reactive). At the end of a measuring period‚ the average power factor is calculated as follows: Some equipment draws current that is heavily distorted from the ideal sine wave. This generates harmonics‚ which increase the current by another component‚ the harmonic current Ih. These harmonic currents reduce the power factor to: It is important to recall that the Pf is part of a complex component on our system

An object in simple harmonic motion experiences a net force which relates to Hooke’s law. Hooke’s law states “Force is directly proportional to the displacement from the equilibrium position and acts

Prelab 3 1: The operations involved in the modulation of DSB-SC are: A message signal and carrier signal are fed in to a mixer which effectively modulates the message signal. The figure below demonstrates this step: Mathematically‚ this is expressed as the following: The resultant waveform can be demodulated by multiplying the modulated signal by the carrier signal of the same frequency and then using the low pass filter to filter out the remaining frequencies to get the frequency required

and Brett M. Nee‚ Student Member‚ IEEE Abstract—A modulation-based method for generating pulse waveforms with selective harmonic elimination is proposed. Harmonic elimination‚ traditionally digital‚ is shown to be achievable by comparison of a sine wave with modified triangle carrier. The method can be used to calculate easily and quickly the desired waveform without solution of coupled transcendental equations. Index Terms—Pulsewidth modulation (PWM)‚ selective harmonic elimination (SHE).
