Digital 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 کاملUltra-Low-Energy DSP Processor Design for Many-Core Parallel Applications
Background and Objectives: Digital signal processors are widely used in energy constrained applications in which battery lifetime is a critical concern. Accordingly, designing ultra-low-energy processors is a major concern. In this work and in the first step, we propose a sub-threshold DSP processor. Methods: As our baseline architecture, we use a modified version of an existing ultra-low-power...
متن کاملDigital 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 کاملApplications of a digital audio-signal processor in T.V. sets
Digital audio-signal processors are already being used in professional applications (mixing consoles, artificial reverberation etc.). In this paper some applications of such a device in a consumer product, e.g. a television set, are discussed. Apart from well-known functions such as tone, volume and balance control the following rather new functions can also be implemented using a digital proce...
