Sharpened FIR Filters by Matthew Donadio, Night Kitchen Interactive |
|
 |
What would you do in the following situation? Let's say you are diagnosing a DSP system problem in the field. You have your trusty laptop with your development system and an emulator. You figure out that there was a problem with the system specifications and a symmetric FIR filter in the software won't do the job; it needs reduced passband ripple, or maybe more stopband attenuation. You then realize you don't have any filter design software on the laptop, and the customer is getting angry. The answer is easy: You can take the existing filter and sharpen it. more>> |

Hybrid Floating Point Technique Yields 1.2 Gigasample Per Second 32 to 2048 point Floating Point FFT in a single FPGA by Ray Andraka, Andraka Consulting |
|
 |
Hardware Digital Signal Processing, especially hardware targeted to FPGAs, has traditionally been done using fixed point arithmetic, mainly due to the high cost associated with implementing floating point arithmetic. That cost comes in the form of increased circuit complexity. The increase circuit complexity usually also degrades maximum clock performance. Certain applications demand the dynamic range offered by floating point hardware, and yet require the speeds and circuit density usually associated with fixed point hardware. The Fourier transform is one DSP building block that frequently requires floating point dynamic range. more>> |
