A decimal to bcd encoder has 10 input lines D0 to D9 and 4 output lines Y0 to Y3. Below is the truth table for a decimal to bcd encoder. From the truth table, the outputs can be expressed by Continue reading →

An encoder has 2n or fewer input lines, only one of which is in the “1” state at a particular time and an n-bit code is generated on “n” output lines depending upon which of the input is excited.  In Continue reading →
