My concern is that a lot of “noise” will be generated by engines such as ChatGPT, computer … WebWith this assumption the quantization noise power is. P q = 1 q ∫ − q / 2 q / 2 x 2 d x = q 2 12 = V r e f 2 12 ⋅ 2 2 N. The signal power is given by. P x = V m a x 2 2 with V m a x = 100 m V. The factor 1 / 2 in the signal power comes from the fact that the input is sinusoidal, i.e. its power is given by half its maximum value.

The ‘Signal-to-Noise’ ratio or, SNR (in short), is a metric that describes the signal performance in the presence of wireless channel noise (interference). In the linear scale, the SNR is the ratio of the signal power to the noise power. The wireless channel is never noise-free. tsing yi station 香港
