Allen, Texas Recent start-up Quickfilter Technologies Inc. unveiled its first product a four-channel programmable signal converter (PSC) that it said will enable complete four-channel signal processing and filtering in minutes.
The QF4A512 PSC features a 16-bit analog-to-digital (A/D) converter with four differential or single ended inputs. Each channel can be individually programmed for gain, anti-aliasing filter cutoff frequency, A/D converter sampling frequency, and the filtering requirements unique to that input (up to 512 taps per channel). The four independent finite impulse response (FIR) filters are capable of generating brick wall filters. As an example, a lowpass filter with a 1-kHz cutoff frequency, 80 dB of rejection, and a total transition band of only 5 Hz can be designed in minutes, said Bob Silco, CEO of the fabless IC company. Each channel can have a different signal bandwidth, A/D sample rate, and filter function design.

Quickfilter's QF4A512 signal converter product line allows engineers to design and implement a custom circuit for signal conditioning, conversion and processing without the cost and complexity of designing a circuit board containing discrete components in addition to programming a digital signal processing (DSP), Silco said.
Quickfilter's design software has been created for rapid configuration and filter design, according to Silco. Filter templates are selectable in Quickfilter's design software for a variety of applications. "By making it extremely easy to program and re-program at any time, we are enabling our customers to personalize their products, implement just-in-time manufacturing and create new products," he said.
The QF4A512 PSC is suited for industrial control, machine monitoring, medical monitoring and diagnostics, industrial smart sensors, homeland security monitoring, and a variety of other applications.
The Quickfilter development kit includes a Windows-based graphical user interface (GUI) that prompts engineers for all the relevant filter specifications of any common digital filter type (lowpass, notched lowpass, highpass, bandpass, dual bandpass, bandstop, and dual bandstop). The user configures the rest of the chip for parameters such as gain, A/D converter sampling rate, power consumption, output speeds, and run configurations. The software then loads the information into the chip and using the included white noise file, or other signal source, the engineer views the signal output on his computer screen as a fast Fourier transform (FFT) graph.
A complete development kit for the QF4A512 PSC is available for $199. The kit includes all hardware and software necessary to design, implement, and test a complete filter design, including a development card, input and output cables, software and sample signal input files.
