The circuit in Figure 1 uses a MAX232 IC from Maxim to convert RS-232 voltage levels to TTL levels (Reference 1). A 74HC4051 from Texas Instruments lets you select any of four digital inputs and route ...

A combinational circuit design is shown below in Figure 1. Now, if we write the simulation statements for this circuit in alphabetical order by gate name (G1 to G5) for input vector, A=1, B=0, C=0, ...

As a demonstration of the complex circuits possible with our NOR gates, six two-input, one-output digital logic circuits were built by integrating up to five NOR gate cassettes into various ...

A digital input in a circuit. Figure caption, A single pole, single throw (SPST) switch is an example of a digital input. When the switch is open the bulb is off and when closed it is on.
