The design of Finite Impulse Response (FIR) filters has evolved into a sophisticated discipline that balances signal-processing performance with hardware efficiency. Innovations in FIR filter design ...

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 ...

Bit Layer Multiplier Accumulator (BLMAC) is an efficient method to perform dot products without multiplications that exploits the bit level sparsity of the weights. A total of 1,980,000 low, high, ...

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 ...

Why use FIR filters, anyway? With the availability of easy-to-use IIR filters in Cypress Semiconductor’s PSoC Creator’s Filter tool, I’ve spent a lot of time over the years telling people the ways in ...

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 ...

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 ...

Finally, we perform a 1680-point inverse DFT on H(m) to obtain the interpolated h(k) impulse response (coefficients), shown in Figure 13–73(b), for our desired filter. (The ten-fold compression of the ...
