Logic is the beginning of wisdom, not the end.

—Mr. Spock 

 

 

In digital electronics, voltages are restricted to just two values, represented as 0 and 1.  Amazingly, combinations of these two numbers govern all modern technology.  This course introduces combinational and sequential logic.  Students will acquire and apply a detailed understanding of all of the following:  Boolean algebra, K maps, combinational circuits including multiplexers and arithmetic logic units, sequential circuits containing flip-flops and counters, and circuits that transmit and receive serial data.  Students will develop skills in Verilog, a hardware description language used in industry to implement circuits containing thousands or millions of logic gates.  

 

            Grades will be determined as follows:

 

            Project 1:  due October 23                                           25%

            Project 2:  due December 18                                        25%

            Test 1, Test 2                                                               25% each
