Power-spectral plots generated by frequency sweeps or fast Fourier transforms (FFTs) can show you a signal’s frequency content, but sometimes an FFT provides more detail than you need. If you design ...

The SC-30 is a Type 1 real-time octave band analyzer with a frequency range from 31.5 Hz to 16 kHz. With a single 23 to 140 dB dynamic range and a memory of 984 hours of 1-second measurements, it ...

In a 16-pin plastic SOIC package, the MSSCSA packs a 1/6-octave wide, six-band spectrum analyzer. The device's normalized center frequencies are set at 1.12246, 1.2599, 1.4142, 1.5874, 1.78179, and 2, ...

RESULTS of an Armour Research Foundation program, prompted by ATA interest in truck exhaust noise problems, are described here. It is shown that exhaust-noise measurements can be made using an octave ...
