Use of DFOD
The main purpose of the DFOD is to provide improved accuracy when differentiating digital signals with wide frequency ranges or high sample rates. By using a fractional-order differential equation instead of a traditional order equation, it can accurately capture and represent the characteristics of a wide variety of signal shapes. Moreover, the fractional-order filtering process helps retain accurate resolution and frequency information at higher frequencies compared to conventional filters. This makes it suitable for applications including signal processing, image processing, and other areas where high accuracy and precision are required.
Benefits
One major benefit of the DFOD is its ability to handle signals with both low and high frequencies without incurring large errors in accuracy or resolution over time. Further, since the filtering process takes place in the time domain rather than in the frequency domain, less computational complexity is involved compared to conventional filters such as Fourier transforms or finite impulse responses (FIR). Also, by using fractional order equations instead of traditional linear differential equations it allows signal parameters like signal duration and amplitude to be manipulated more freely without affecting performance or precision significantly making it highly customizable according to specific requirements.
