How is SQNR calculated?

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.

What does SQNR stand for?

Signal-to-quantization-noise ratio (SQNR or SN_qR) is widely used quality measure in analysing digitizing schemes such as pulse-code modulation (PCM).

What is the SQNR of quantization in decibel?

The SQNR in dB is approximately equal to 6 times the number of bits of the analog-to-digital converter (ADC). For example, the maximum SQNR for 16 bits is approximately 96dB.

What is quantization noise formula?

Assuming that the quantization error is random it can be treated as white noise. The quantization noise power and RMS quantization voltage for an ADC is given by the equation: [4] A quantized signal sampled at frequency f_s has all of its noise power folded into the frequency band 0 <= f <= f_s/2.
