Priority encoders can be easily connected in arrays to make larger encoders, such as one 16-to-4 encoder made from six 4-to-2 priority encoders – four 4-to-2 encoders having the signal source connected to their inputs, and the two remaining encoders take the output of the first four as input.

If the input circuit can guarantee at most a single-active input, a simple encoder is a better choice than a priority encoder, since it requires less logic to implement. However, a simple encoder can generate an incorrect output when more than a single input is active, so a priority encoder is required in such cases.
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
Audio encoder, converts digital audio to analog audio signals; Video encoder, converts digital video to analog video signals; Simple encoder, assigns a binary code to an active input line; Priority encoder, outputs a binary code representing the highest-priority active input; 8b/10b encoder, creates DC balance on a communication transmission line

Redding averages 5.48 inches in February but could see 4-8 inches by Wednesday, AccuWeather said. This storm won't move on to create a path of destruction in the nation's interior, Zehr said.
It uses three output levels: + (positive pulse), 0 (no pulse), and; − (negative pulse). This means we have 2 4 = 16 input combinations to represent, using 3 3 = 27 output combinations. 000 is not used to avoid long periods without a transition. 4B3T uses a paired disparity code to achieve an overall zero DC bias: six triplets are used which have no DC component (0+−, 0−+, +0−, −0 ...
