Digital Signal Processor Trends
During the past decade digital signal processors (DSPs) have hit critical mass for high-volume applications (Figure 1). Today, the entire digital wireless industry operates with DSP-enabled handsets and base stations. The mass-storage industry depends on DSPs to produce hard-disk drives and digital versatile disc players. Ever-increasing numbers of digital subscriber line and cable modems, line...
متن کاملDigital Signal Processor ( DSP ) based 1 / f α noise generator
1/f noise is present in several natural and artificial systems, and even though it was discovered several years ago, it is still not completely understood. Due to the lack of an universal model, the main methods of investigating a system where 1/f noise is present are numerical simulations and real measurements. The second method can lead to more adequate results, since it is free from numerica...
متن کاملA DSP-Based Audio Signal Processor
The ASP consists of several components: a digital beat-frequency oscillator (BFO), selectable band-pass filters for CW, SSB and other digital modes, a denoiser based on the least-mean-squares (LMS) technique and a Wiener-filter autonotcher (removing carriers or heterodynes). Several advanced concepts are applied in this project, such as multirate processing, adaptive filtering and frequency shi...
متن کاملA Novel Sensorless Control Technique for Permanent Magnet Synchronous Motor (pmsm) Using Digital Signal Processor (dsp)
A novel sensorless control scheme for Permanent Magnet Synchronous Motor (PMSM) is presented. The rotor position estimation is obtained by the position perturbation algorithm, and high performance of the PMSM is achieved by using the vector control technique. DSP56005 is used to realize the position estimation and vecor control algorithms. Experimental results are presented to substantiate the ...
