What is the value of quantization noise power?
With a uniform amplitude distribution, the quantization noise power is equal to LSB212 L S B 2 12 . The power spectral density of the quantization noise is frequency independent (it's white noise). For a sine wave, we can find the maximum SNR of an ideal N-bit quantizer as SNR=1.76+6.02N.
What is the value of SQNR for 16 level quantizer?
Uniform quantization and the 6 dB/bit approximation
=65536 and SQNR = 16×6 = 96 dB.
What is meant by quantizing noise?
Quantization noise is the effect of representing an analog continuous signal with a discrete number (digital signal). The rounding error is referred to as quantization noise. The quantization noise is nearly random (at least for high resolution digitizers) and is treated as a noise source.
How do you calculate SNR quantization?
Furthermore, for power, SNR = 20 log (S ÷ N) and for voltage, SNR = 10 log (S ÷ N). Also, the resulting calculation is the SNR in decibels. For example, your measured noise value (N) is 2 microvolts, and your signal (S) is 300 millivolts.
