Webthat take low resolution DAC into account. Here we propose digital dithering xat the transmitter to miti-gate the distortions caused by the low-resolution DAC. The use cmof dithering to reduce resolution of the ADC is well known. [27]-[30]. In [31] was shown that pseudo-noise injec-tion improves the quality of images. The idea of using dither WebAudio bit depth. An analog signal (in red) encoded to 4-bit PCM digital samples (in blue); the bit depth is four, so each sample's amplitude is one of 16 possible values. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample. simplified drawing of a stereo microscope
