COMPARATOR DESING In the experiment, a ''COMPARATOR'' for 3 bits A and 2 bits B will be designed. EXPERIMENT 1 Materials to be used in the experiment: - 1 piece 7485 - 8 LEDs and pre-resistors for LEDs The circuit diagram is given in Figure 1. A2, A1, A0, B1, B0 and will be used for the outputs of the comparator. Circuit on breadboard and simulation environment.

'''''use multimism or proteus for simulation'''''

'''''use tinkercad for breadboard'''''

'''''Run the circuit by changing the states of the comparator and, for each case, the output Observe the LEDs.'''''

'''''Apply the situations in Table 1 and fill out the outputs. Display in any situation Save the image'''''
