cycle of a periodic waveform. By a simple inspection process, list the lowest five froquencies (including de if present) in the spectrum. 7-02a

Find the phase difference for the given waveform if the time base switch is at 2 ms/div. S O a. 90⁰ O b. 45⁰ O c. 180° O d. 30° period VA L 3 5

How long does it take for a 2kHz sine wave to reach a phase angle of 50˚?       830µs     500µs     10.5µs     69.4µs

True or false 6. Sine wave leading the cosine wave by 90°. 7. If the voltage across a coil is sinusoidal in nature, the resulting current will also have sinusoidal characteristics. 8. As the angular velocity increases the period for a waveform increases too. 9. An angle of 0.87 equivalent to 45º. 10. You can examine the leading and lagging properties for waveforms if they have the same frequency only.
