as observe how the different types are distinguished. It was a vital part in fully understanding that shift registers are a type of sequential logic circuit closely related to digital counters. Section OneMethod & Procedure:The methods and procedures for this lab assignment were quite simple to follow and accomplish. We simply had to observe the registers as they operated. The first circuit instructed us to complete the related problem as well.Circuit F11-062
In this section we were instructed to simply observe the operation of a 4-bit parallel in/serial out register. The MultiSim Logic Analyzer was already connected, along with a Word Generator.Circuit F11-19Again, we were instructed to simply observe the operation, this time of a 4-bit Bidirectional Shift Register.5
Circuit F11-26Observe the operation of a 10-bit Ring Counter.6
SECTION 2Circuit P11-55For this circuit we were instructed to observe the operation of the 10-bit Ring Counter and identify any faults.7
We see that none of the outputs are registering, therefore there must be a fault with the outputs of the data input register. Conclusion:This section showed how to isolate a fault in a counter and determine what might be wrong. This lab was essential in helping us understand the differences in the types of registers and howthe operate. It allowed us to see just how much they are like digital counters as well. 8
