Every periodic signal can be decomposed to a sum (finite or infinite) of sines and cosines according to fourier analysis.
The sinusoidal signal is called a basic signal because, by Fourier Analysis, you can not further reduce it. It is one sine wave of one frequency of one amplitude of one phase. It has no harmonics. If you converted it from time domain to frequency domain you would only get one line, at the fundamental frequency.
if a signal is not a pure sine wave it must contain harmonics
Sine wave is considered as the AC signal because it starts at 0 amplitude and it captures the alternating nature of the signal. Cosine wave is just a phase shift of the sine wave and represents the same signal. So, either sine or cosine wave can be used to represent AC signals. However, sine wave is more conventionally used.
A sine signal, shifted 90 degrees in Phase. It otherwise is practically the same. Also, when a cosine signal coexists with a sine signal, it can be on the same frequency without interfering. The consequence of that is ... Two Channels can exist on the same frequency which are the Sine and the Cosine, and they can be separated in a receiver that can process and separate both of those Phases.
The three basic waveforms are Sine, Triangle and Square waves. For transmitting, the only one that matters is the Sine wave because it has no harmonics of its own. A "harmonic" is an unwanted emanation running at an exact multiple of the frequency you're trying to use.
It is more reasonable to use square wave rather than sine wave signal to determine slew rate. Both signal sources serve as a functional generator with the sine wave providing high purity waves.Ê
The sine wave symbol is significant in signal processing because it represents a fundamental waveform that can be used to analyze and manipulate various types of signals. Sine waves have specific properties that make them useful for tasks such as filtering, modulation, and frequency analysis in signal processing applications.
Should be a sine ( or cosine) wave.
