The Odd Discrete Fourier Transform (ODFT) is used in many modern audio codecs which employ the Modified Discrete Cosine Transform (MDCT) for efficient signal representation. The ODFT is used ...

One of the best things about working at Tektronix is all of the smart test engineers floating around our Beaverton, OR campus, and around the world. In this post, engineer Ian Dees goes “behind the ...

Time-frequency analysis has emerged as a vital tool in understanding signals and systems by providing simultaneous information about a signal’s temporal and spectral features. This field has led to ...

The Fourier transform underpins so much of our technological lives, in most cases probably without our realising it. The ability to mathematically split a waveform into its frequency components and ...

FTIR deals with the infrared region of the electromagnetic spectrum, and it works by measuring how much light is absorbed by the bonds of vibrating molecules to provide a molecular fingerprint. The ...
