👉 Radio mathematics, also known as harmonic analysis or Fourier analysis, is a branch of mathematics that deals with representing functions or signals as the superposition of basic waves, typically sine and cosine functions. This approach is fundamental in signal processing, physics, and engineering, allowing for the decomposition of complex signals into simpler components that are easier to analyze and manipulate. The core idea is that any periodic function can be expressed as a sum of sinusoidal functions with different frequencies, amplitudes, and phases. This decomposition is particularly useful for tasks like filtering, modulation analysis, and solving partial differential equations. The Fourier Transform is a key tool in this field, converting signals from the time domain to the frequency domain, where it becomes easier to identify and process specific frequency components.
