Fast Fourier Transform (FFT) Spectrum Analyzers and Signal Analyzers are instruments used to convert time-domain signals into their frequency-domain representations. They achieve this by digitizing ...

Many of today's digital oscilloscopes include fast-Fourier-transform (FFT) capability for frequency-domain analysis. This feature is especially valuable for oscilloscope users who have limited or no ...

The bank-of-filters technique is not common in general electronic instrumentation but has been used in some applications, such as low-frequency audio meters (1/3-octave spectrum analyzers). This ...

Fourier transform spectroscopy (FTS) has become an indispensable tool for the quantification and monitoring of atmospheric constituents. By measuring the interference pattern—known as an interferogram ...

A spectrum analyzer is a device that measures and displays Signal amplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis ...

What is real-time spectrum analysis? Spectrum (FFT) vs. real-time mode for viewing spikes. What is needed to test for conducted and radiated emissions? If you’ve ever tried to perform ...

This audio spectrum analyzer utilizes an ARM7 LPC2138 microcontroller to create an FFT algorithm while performing digital signal processing without the use of special DSP processor. This audio ...

Having a scope in a home lab used to be a real luxury, but these days, its fairly common for the home gamer to have a sophisticated storage scope (or two) hanging around. Dedicated spectrum analyzers ...

Over at Quanta Magazine [Shalma Wegsman] asks What Is the Fourier Transform? [Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation ...
