(A)Element 3-7 Waveforms Flashcards
1
Q
What is a sine wave?
A
a wave whose amplitude at any given instant can be represented by the projection of a point on a wheel rotating at uniform speed
2
Q
How many degrees are there in one complete sine wave cycle?
A
360 degrees (wheel)
3
Q
What type of wave is made up of sine waves of the fundamental frequency and all the odd harmonics?
A
a square wave (odd harmonics)
4
Q
What is the description of a square wave?
A
a wave that abruptly changes back and forth between two voltage levels and stays at these levels for equal amounts of time
5
Q
What type of wave is made up of sine waves at the fundamental frequency and all harmonics?
A
Sawtooth wave
6
Q
What type of wave is characterized by a rise time and signific ally faster than the fall time?
A
Sawtooth wave
