Question
The circuit that is used to interface the keyboard to the PC is _________a.Priority Encoderb.Priority decoderc.Multiplexersd.8:1 MUX
Solution
The circuit that is used to interface the keyboard to the PC is a. Priority Encoder.
Here's why:
A keyboard is an input device that sends signals to a computer by pressing keys. The keyboard uses a circuit called a priority encoder to convert the signals from the keys into a binary code that the computer can understand.
The priority encoder has multiple input lines and one output line. When a key is pressed, the corresponding input line is activated. The priority encoder then converts the activated input line into a binary code. This binary code is sent to the computer, which interprets it as a specific key press.
Therefore, the correct answer is a. Priority Encoder.

A priority encoder is an encoder circuit with priority. If 2 or more inputs are equal to 1, the input with the highest priority will take precedence. The truth table of a 4-input priority encoder is shown below. An output V is added which is set to1 when one or more inputs are equal to 1; otherwise V is 0. The two outputs x and y are not inspected when V equals 0 and hence they are specified as don′t care outputs. Note that whereas x′s in output columns represent don′t care outputs, the x′s in the input columns are useful for representing a truth table in compact form. For example, input X100 represents the 2 input combinations: 0100 and 1100. The simplified SOP expressions for X is
