SINUSOIDAL WAVEFORM DEFINE PHASE,
Phase is another measurement of the sine wave, and it indicates where the wave is in its cycle. It is measured in degrees (0°-360°) or radians (0-2π) and is denoted with the Greek symbol Phi (ϕ). Figure defines Different phases of a sine wave.
Mathematical Representation
The mathematical representation of sinusoidal signals is given by:
SINUSOIDAL WAVEFORM DEFINE PERIOD,
The period of a sinusoidal waveform is the time it takes to complete one cycle of the waveform. It is measured in seconds (s) and is inversely related to the frequency of the waveform. The formula for the period is T = 1/f, where T is the period and f is the frequency in Hertz (Hz).
Here are some other terms related to sinusoidal waveforms:
- Cycle: A complete set of positive and negative values of a waveform. A sinusoidal waveform cycle includes one positive half cycle and one negative half cycle.
- Frequency: The number of cycles completed in one second, measured in Hertz (Hz).
- Angular frequency: The frequency expressed in electrical radians per second.
- Amplitude: The peak height of a waveform.
SINUSOIDAL WAVEFORM DEFINE FREQUENCY,
The frequency of a sinusoidal waveform is the number of times a wave completes a cycle in one second, and is measured in hertz (Hz):
Frequency | Definition |
|---|---|
Definition | Number of cycles completed in one second |
Unit | Hertz (Hz) |
Frequency is a fundamental characteristic of sinusoidal waveforms that determines how fast the wave oscillates. It's a key parameter in communication systems, signal processing, and power electronics.
The relationship between frequency and period is given by the equation f = 1/T.
