Interpolation and Decimation Options Enable Better Performance and Lower-Power Filters to be Implemented in Altera PLDs Delivers Significant Performance and Cost Benefits over DSP Processors and ...

A demonstration of FIR filters in operation completes this series of columns. For this demonstration, I used an ARM mbed module with an NXP LPC1768 microcontroller (ARM Cortex-M3 processor). Although ...

The first part of this series described how data flows through processing steps that create a moving average of stock prices over 65 days. Finite-impulse-response (FIR) filters use the same data-flow ...

In this paper, we first review in detail the basic building blocks of reconfigurable devices, essentially, the field-programmable gate arrays, then we describes a high-speed, reconfigurable Systolic ...

FIR filters used for signal manipulation in the digital domain have either a symmetric or anti-symmetric impulse response, i.e., where N is the order of filter. This Design Idea extends the same ...

Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...

Emphasizing achievable results and conclusions through numerous worked examples, while reducing the use of mathematics for an easier grasp of the concepts, this text presents DSP principles, ...

With the constant downward price pressure on consumer electronics devices, one area that typically gets compromised is audio quality. This compromise is often reflected by the manufacturers' choice of ...
