A spectrum analyzer is a measurement tool that displays real-time frequency analysis of incoming audio signals. The frequency spectrum is generated by applying a Fourier transform to the time-domain signal. The audio frequency spectrum refers to the number of times when a sound wave repeats per second.

acoustics of a given room). Now, plot the spectrum of this signal by typing: plot_spectrum(y,FS); As you will see, this audio signal contains frequencies from about 100Hz to 10,000Hz as the filename suggests. While the spectrum shows that these frequencies are present during the 5 second duration of

• Sinusoidal signals are important because they can be used to synthesize any signal – An arbitrary signal can be expressed as a sum of many sinusoidal signals with different frequencies, amplitudes and phases • Music notes are essentially sinusoids at different frequencies shift) (time Phase φ: Amplitude: period: / 1 cond) (cycles/se frequency :) 2 cos()

Although the operation could provide various forms of spectra, most often, “signal frequency spectrum” refers to the amplitude spectrum of the signal. Figure 1 shows the amplitude spectrum of a 10 MHz 1 V or 0.707 VRMS sine wave on Analog Arts’ SL957 spectrum analyzer. An ideal sine wave has only one frequency component. So intuitively, in its spectrum plot we …

From the right side of the interface, you can set dB limit (from -160 dBu to 20 dBu), and frequency limit (10 Hz to 50KHz) to provide sufficient dynamic range for signal fluctuation. Thus, lets you perform audio spectrum analysis in a better way.

We are plotting frequencies ranging from 0 to 8kHz because our signal was sampled at 16k sampling rate and according to the Nyquist sampling theorem, it should only posses frequencies ≤ 8000Hz (16000/2). Strong frequencies are ranging from 0 to 1kHz only because this audio clip was human speech.
