Using “Reversed Amazon Echo” Techniques on a Train Whistle

On December 19, 2019 in All, Audio, Computing by Charles Byers

Directional sound pickup using microphone arrays is being used in devices like the Amazon Echo. What if this technique could be reversed, controlling the sound fields of speaker arrays using digital-signal processing algorithms? This blog looks at a train whistle and how applying these techniques could prove beneficial to the application.

APEC 2015: Powering FPGAs and DSPs

On March 18, 2015 in Power by Aimee Kalnoskas

The Charlotte, North Carolina Convention Center, home to APEC 2015, is a decent size. But with nearly 4500 attendees (a 10% increase over last year), hundreds of technical and industry sessions, and nearly 250 exhibitors, it certainly packed a lot into one space.

The “Death of the Downconverter”? Not Just Yet

On April 2, 2014 in RF by Barry Manz

The impact of converting analog signals to digital form is one of the greatest advances the electronics industry has ever achieved. Although today almost every consumer, industrial, commercial, and military system depends on this capability, one of the last remaining outliers is directly converting analog signals at microwave frequencies into digital data streams without using large amounts of intervening microwave hardware (i.e., downconverters).
