How are ADC and DAC organized and operated? Part 2
The main difference between PDM and PWM DAC is that the maximum
pulse width in PWM is not equal to a power of two (e.g. for MASH it is
equals 11).
DACs with oversampling and a small number of real bits have
significantly better linearity than parallel DACs with the same
tiva bit depth. The output waveform of these DACs is
fight a useful signal, framed by a significant amount of high frequency
total noise, the main energy of which is far enough away from
the higher frequency of the useful signal and thus effectively suppresses even
the simplest analog filter.
The effective bit width of a Delta-Sigma DAC is generally determined from a pair of
output signal meters – noise level and non-linear distortion factor
zheniya characteristic of a parallel DAC of a certain bit depth. When
the effective bit capacity of the Delta-Sigma DAC can significantly exceed
shake the bit width of your input signal, for example a DAC for a 16 bit
The digital signal can have an effective bit width of 18, 20 and
moreover, smoothing the original signal, reducing the influence of quantum errors on it.
and thus make it more comfortable to listen.
DACs are “straightforward” devices that convert to
it is easier and faster than ADCs, which are mostly later
and slower devices.
