1. What are the phase angles between the two sine waves in parts (a) and (b) of fig. shown below. B 0° 45° 90° 135° -30°/0° (a) (b)

A voltage wave of 250 kHz has a Vmax-5 V and Vmin=-35 V. The duty cycle of this wave is 0.875. This voltage waveform has been applied across a 2.5 µH inductor for a very long time so that steady state has been achieved. Diagrams of the wave parameters and circuit are shown in this figure: L What is the average voltage of this wave? Average voltage = 35 V Voltage (arb, unit) 1.25 Minimum current: -3.5€ Amps 1 0.75 0.5 0.25 0 4.25 05 Have you integrated the wave over full cycle? 4.75 4 -1.25 Vmax 0.5 Vmin What is the average current flowing through the inductor? Average current = 3.56 A 15 Period/s On average, there is no power consumed by the inductor. Have you considered this? What are the maximum and minimum currents that flow through the inductor? Maximum current: 0.50 Amps D= 25 TH TH Have you used the relationship for current and voltage in an inductor? Have you considered the slope of the current wave?

From the information in the table below, draw on graph paper the sine wave, square wave, and triangle wave

Question a, Draw a sine wave with a frequency of 250 Hz that lasts for a duration of 12 ms and varies between an amplitude range of -5 and 5 V. Make sure to plot all cycles of the wave that fit within the duration of 12 ms and mark the labels and values of the axes completely. b, How many cycles can fit within the same duration of 12 ms if the frequency of the sine wave in the previous problem is doubled ?
