This is usually modeled as a uniform random fluctuation between −1/2 LSB and +1/2 LSB.
Introduced in early 1985, the first "VideoDAC" had an output clock rate of up to 75 MHz and 1/4 LSB accuracy—3-8 times better than typical contemporary devices.

As such, the bit order of the octet access is the bit order of the accessing device, which is usually LSB 0; and serial transmission is arranged such that the least significant bit of each octet is transmitted first.
ALGOL 68's elem operator is effectively "MSB 1 bit numbering" as the bits are numbered from left to right with the first bit (bits elem 1) being the "most significant bit" and the expression (bits elem bits width) giving the "least significant bit".
