Audio Spectrum Analyzer Uses 256-Point FFT
This
FFT development board from RHDC Services features a fully functional
audio band
spectrum analyzer for just £59.95 ($95.35). An ultra low power Sharp
96x96-pixel display and judicious selection of processor and peripheral
components yields a module that consumes only 3 μA in a static
state and 1.3 mA while FFT'ing. Per their website, "The FFTD1A
can typically display an image and maintain a real time clock using
less than 10µW. Assuming a CR2032 coin-cell delivers 200mAh, that's
around 6 years battery life."
FFT Designer
software together with the FFTD1A development board allows users to
develop application software that performs Fourier analysis with a 12-bit,
200 ksps input and a 50 dB SFDR. Add a simple mixer, LO, and filter
to extend the useful range to just about any frequency band. RHDC Services
also provides RF R&D and communication systems engineering services.

About RF Cafe RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived... |
