Quantization Example
about sampling and DSP on my own. I have a hard time to understand how the quantization error results in noise. I think I miss a fundamental understanding but can't tell what it is. So how does the quantization error generate noise? noise sampling share|improve this question asked Jul 15 '12 at 19:29 Jan Deinhard 1485 It's more distortion than noise. It depends on the signal, and is not random. –endolith Jul 15 '12 at 20:48 endolith, I think what quantization error in pcm I don't understand is how the error results in frequencies. –Jan Deinhard Jul 15 '12 at 21:04 2 distortion always produces additional frequencies. if you distort a sine wave, it becomes a different repetitive waveform. any repetitive waveform other than a sine wave is made up of multiple frequencies. –endolith Jul 15 '12 at 22:58 1 As @endolith has mentioned, let us assume you have a very bad ADC, such that you give it a pure tone, but get a signal that looks like a sine but has big steps in it. (So now your signal looks like a staircase that is going up and down with the original sine.) Now, you know intuitively that a step is composed of many frequencies. This is how an ADC will add frequencies as you are asking. It is a non-linear operation btw. If it was linear, you could not make new frequencies, only superimpose many of them together. –Mohammad Jul 16 '12 at 14:33 add a comment| 3 Answers 3 active oldest votes up vote 6 down vote accepted Suppose I have a multitone signal (six carriers, at ±1/1000, ±2/1000 and ±7/1000 of sampling frequency) x = (1:1000); wave = sin(x/1000*2*pi) + sin(x/1000*2*pi*2) + sin(x/1000*2*pi*7); which is quantized using a 14-bit ADC wave_quant = round(wave * 16384) / 16384; The difference wave_qnoise = wave_quant - wave; gives the quantization error The corresponding spectrum wave_qnoise_freq = mag(fftshift(fft(wave_qnoise)) / sqrt(1000)); shows the generated noise floor across the entire spectrum.

Activities in event-based systems are triggered in response to events usually representing a significant change of the state of controlled or monitored physical variables. Event-based systems adopt a model of calls for resources only if it is necessary, and therefore, they are characterized by efficient utilization of communication bandwidth, computation capability, and energy budget. Currently, the economical use of constrained technical resources is a critical issue in various application domains because many systems become increasingly networked, wireless, and spatially distributed.
