Parseval’s theorem

Parseval’s theorem

by

Parseval’s theorem, also known as Plancherel’s theorem or Rayleigh’s energy theorem, is a fundamental result in Fourier analysis and signal processing. It relates the energy (or power) of a function (or signal) to the energy (or power) of its Fourier transform. In essence, it states that the total energy remains the same whether you calculate … Read more

Significance of RMS (Root Mean Square) value

by

Root Mean Square (RMS) value is the most important parameter that signifies the size of a signal. Defining the term “size”: In signal processing, a signal is viewed as a function of time. The term “size of a signal” is used to represent “strength of the signal”. It is crucial to know the “size” of … Read more
