Multisinhälysignaali
Multisinhälysignaali, also known as a multi-sinusoidal signal, is a signal composed of the sum of multiple sinusoidal waveforms. Each sinusoid in the sum has its own unique amplitude, frequency, and phase. This type of signal is fundamental in signal processing and electrical engineering, as many complex waveforms can be represented as a combination of sinusoids through Fourier analysis.
The general mathematical representation of a multisinhälysignaali can be expressed as:
$x(t) = \sum_{n=1}^{N} A_n \cos(2\pi f_n t + \phi_n)$
where $A_n$ is the amplitude of the n-th sinusoid, $f_n$ is its frequency, $\phi_n$ is its phase,
Multisinhälysignaalit are prevalent in nature and technology. For instance, musical notes are often perceived as complex
