Understanding the 1:4 MUX Configuration
A 1:4 multiplexer (MUX) is a digital switch that selects one of several input signals and forwards the selected input to a single output line. The selection is determined by control signals.
Control Signals
- C1 = 1: This is the most significant control signal.
- C0 = 0: This is the least significant control signal.
Input Configuration
In a 1:4 MUX, there are four inputs, typically denoted as I0, I1, I2, and I3. The control signals determine which input is directed to the output based on the following selection criteria:
- 00: Selects Input I0
- 01: Selects Input I1
- 10: Selects Input I2
- 11: Selects Input I3
Output Determination
Given the control signals C1=1 and C0=0, we can convert these binary values to decimal to determine the selected input:
- C1C0 = 10 (in binary) = 2 (in decimal)
Thus, when C1=1 and C0=0:
- Selected Input: I2
Final Output
The output of the 1:4 MUX will be equal to the signal present at Input I2. The specific value of the output will depend on what is fed into Input I2, which is not specified in this case.
In summary, with C1=1 and C0=0, the output of the 1:4 MUX is determined by Input I2.
