这是前两天搭建的H7B0单片机信号采集与计算的模块，利用它的16比特的ADC采集信号，并进行频谱分析，结果显示在OLED屏幕上。计算 2048点的FFT，耗时大约为 10个毫秒左右。下面测试一下，利用 Cortex中的 CMSIS中的 DSP算法库中的FFT，看是否计算速度能够得到提高 ...

Across a range of applications, the two most common functions implemented in FPGA-based high-performance signal processing are finite impulse response (FIR) filters and fast Fourier transforms (FFTs).

Sparse Fourier Transform (SFT) algorithms constitute a transformative approach to spectral analysis by leveraging the inherent sparsity of signals in the frequency domain. In contrast to the ...

The Fast Fourier Transform (FFT) is a widely used algorithm that computes the Discrete Fourier Transform (DFT) using much fewer operations than a direct implementation of the DFT. FFTs are of great ...

Many electronics and digital products use digital signal processing (DSP)algorithms in them. Before any algorithm gets into theproduct, an optimization process is appliedto it. The optimizationprocess ...

SANTA CLARA, Calif. - February 8, 2010 - Tensilica, Inc. today introduced ConnX BBE16, its second generation baseband engine for LTE (long-term evolution) and 4G baseband SOC (system-on-chip) designs.
