About Curasi Software Lab

Curasi Software Lab is an electronic engineering company that specializes in the development of technical application software for Mac OS X. Located in the greater Sacramento area, Curasi Software Lab can provide on-site services to companies located in the Capital region to Silicon Valley. Developed FFTea, a DSP application to design, simulate and export linear FIR filters for both fixed-rate and multirate systems. Filters have symmetric coefficients assuring a constant group delay with zero phase distortion. FFTea's signal generator provides an easy means of producing waveforms at a given sampling frequency for model simulation. Optional additive Gaussian noise included for all functions. Simply scroll to select a function and enter its corresponding parameters. The multirate model consists of an interpolator, decimator, and a single (combined) low pass FIR filter. The multirate FIR filter design can either be auto-generated or performed manually using the FIR filter designer. (FFTea
