Abstract: Using fast Fourier transform (FFT) is indispensable in most signal processing applications. Designing an appropriate algorithm for the implementation of FFT can be efficacious in digital ...

DVB-T dongles based on the Realtek RTL2832U can be used as a cheap SDR (Software-defined radio), since the chip allows transferring the raw I/Q (In-phase / Quadrature) samples to the host, which is ...

Abstract— Multipliers are crucial components in processors and arithmetic logic units. The performance of microsystems, microcontrollers, and DSP processors is often evaluated based on the number of ...

In this article, we investigate what goes into running a daunting math task such as FFT on an Espressif ESP32 development board, admittedly with a little help from a library, a Pmod I2S2 module, and a ...

When listening to music or producing audio, understanding the concept of fundamental frequency is essential. In simple terms, the fundamental frequency is the lowest frequency of a periodic waveform.

Abstract: Fast Fourier Transform (FFT) is a Digital Signal Processing (DSP) technique to compute Discrete Fourier Transform (DFT) in a faster way by utilizing the properties of the twiddle factor.

This paper presents a compact and wearable frequency-modulated continuous-wave (FMCW) radar on a semi-flexible printed circuit board (PCB) for an anti-collision system. This can enable visually ...

Fourier Analysis is one of the most important tools used in signal processing. This work is merely an implementation of the Fast Fourier Transform Algorithm which is used to compute the Discrete ...
