A waveform is a form of a signal moving in a physical medium. There are various types of wave patterns. An instrument called oscilloscope is used to represent a wave on a screen. There are different types of waveforms like the sine wave, square wave, etc. A sine wave forms a trigonometric sine function with time. A square wave is normally used to represent digital information. A sawtooth wave is an expression of waveform amplitude. A sawtooth wave is a non-sinusoidal wave. It is also known as "saw wave". As its name suggests, this waveform resembles the teeth of a saw. A sawtooth wave generally goes upward like a hill and drops down sharply. It can also go downwards and then rise up sharply. This form of wave is known as "reverse sawtooth wave" or "inverse sawtooth wave". A sawtooth wave comprises infinite set of harmonically related sine waves. This wave is often used in sound synthesis.
There are different ways to produce a sawtooth wave such using a built-in oscillator. A saw toothewave can also be generated using a combination of the sine waves. A sawtooth wave is produced by the method of additive synthesis. It is a method used to synthesize sound by adding sinusoidal waves explicitly. A sawtooth wave can be constructed using the infinite fourier series function.
A sine wave is a smooth wave with oscillation. It is used in signal processing, electrical engineering, pure mathematics, and physics. Light waves, sound waves, and ocean waves falls under the classification of sawtooth wave. This wave has sharp edges. The wave form generally ramps upward and drops down sharply. Like the sine waves, the non-sinusoidal sawtooth wave is also capable of producing sound. A sawtooth wave looks different from regular sine waves. Moreover, it produces a different tone. A sawtooth wave contains both even and odd harmonics. The sound clarity is undoubtedly best in the category.
A sawtooth wave is best known for its application in music. Virtual analog music synthesizers generate sawtooth wave. It is also used to replicate string instruments.
Oscilloscopes use sawtooth wave for their horizontal deflection.
A sawtooth wave has strong electromagnetic properties. It has visual applications. This wave can be used to manipulate pixels on the CRT-based screens.
Sawtooth wave has to be triggered in time base generators and power control circuits. A sawtooth wave generator is an external agent often used to make waves. A sawtooth wave generator is made of a simple 555 timer integrated chip and a transistor. By injecting a variable DC voltage into the integrator, a triangular wave generator can be converted into a sawtooth wave generator. A potentiometer is also used. Triangular wave differ from sawtooth wave in its rise time. The rise time and fall time of a triangular wave is the same whereas the rise time is much higher in the case of a sawtooth wave.
