discuss the Types of waveform
Answers
Answer:
mplitude is the strength of a wave's effect; the higher the amplitude, the more the air molecules are displaced. This also translates into loudness for the human ear; increasing a wave's amplitude will increase how loud it seems to us.
The most common periodic waveforms are the sine, triangle, square, and sawtooth.
These waveforms are said to be periodic because the wave they represent can be repeated to produce a constant tone. The faster the wave repeats, the higher the pitch of the sound.
Different waveforms have different harmonics. A harmonic is an additional frequency created by the wave. The sine waveform is unique in that it doesn't have any additional harmonics; it is the fundamental waveform.
To understand why certain waveforms have harmonics, we can attack the problem from the opposite end. Because the sine waveform is the fundamental waveform, it can be used to approximate all the other periodic waveforms, by just adding additional sine waves at the appropriate harmonics, and at the appropriate amplitude levels. In essence, a square wave can be thought of as an infinite number of sine waves, all happening at very specific frequencies and amplitudes
