Efficiently detecting a frequency using a Goertzel filter

Posted on August 25, 2011 by Wilfried Elmenreich

The Goertzel algorithm detects a specific, predetermined frequency in a signal. This can be used to analyze a sound source for the presence of a particular tone. The algorithm is simpler than an FFT and therefore a candidate for small … Continue reading →

An Orchestra of Bits and Bytes: Time-Triggered Advanced Driver Assistance Systems

Posted on August 16, 2011 by Wilfried Elmenreich

Multi-sensor object tracking is an important feature for advanced driver assistance systems in future automobiles. Most state-of-the-art systems cannot guarantee deterministic processing of the sensor values due to unsynchronized sensing and processing units. To overcome this shortcoming we propose a … Continue reading →
