An input used for creating waveforms decides the shape. A square-shaped wave represents digital information as 1 or 0. A sinusoidal wave shows the accurate variation, which happens in an output. It follows the mathematical function, which decides how they are allowed and represented to be interpreted by readers. Sinusoidal waves follow a trigonometric function, which enables them to take the present shape. A square waveform has a harmonic function. A waveform is used for representing different things in different scientific fields such as cosmology, math, biochemistry, and medicine.
Categories of Waveforms
Waveforms are divided into two groups and these are discussed in our Waveform homework help service:
Uni-directional waveform: This waveform is always positive or negative flowing in a forward direction as it does not cross a zero axis point. The common uni-directional waveforms are Clock pulses, square-wave timing signals, and trigger pulses.
A Bi-directional waveform: It is also known as an alternating waveform as it alternates a positive to a negative direction by crossing a zero axis. It goes through periodic alternations in amplitude along with the most common one being Sine-wave.
Whether a waveform is bi-directional, uni-directional, periodic, simple, symmetrical or complex, a waveform includes the common three features:
- Period- It is the length of time that the waveform takes for repeating itself from beginning to end. Its value can be periodic time for sine waves or a Pulse Width for a square wave.
- Amplitude- It is the intensity or magnitude of a signal waveform that is measured in amps or volts
- Frequency- It is the number of times that a waveform repeats itself a second time. This is the reciprocal of Time with the standard frequency unit being Hz or Hertz.
