PRACTICAL 6: STATE MACHINES AND CODE GENERATORS

AIM: INTRODUCTION: This laboratory is about the design, implementation, and testing of a state machine counter and a pulse train generator. The circuits will use JK flip-flops and logic gates to implement the necessary logic operation of the problem. The ICs used are the 7474 JK flip-flops and the 7400 NAND gates . The state machine counter has to follow a State Transition Diagram ...

And People that Make Our Clothes

The paper is a book review of Where Am I Wearing?, a book written by Kelsey Timmerman. The book describes the adventures Timmerman had when he decided to travel to all the factories that had made his clothes. Timmerman describes how he went to Honduras to see where his T-shirt was made, to Bangladesh to see where his underwear was made (23), to Cambodia to see where his jeans were made (107), to China to see where his flip-flops were made (163), and finally to Perry, New York in the United States to see where his shorts were made (226). He ...

A CPU is hardware within a computer that performs the logic, arithmetic and input/output instructions of a computer program. A typical computer can be operated by more than one CPU thus the term multiprocessing. CPUs are assembled on an integrated circuit, and one IC can contain more than one CPU. CPU is made up of two main components namely; arithmetic logic unit ALU and control unit (CU). Arithmetic Logic Unit performs logic and arithmetic operations while CU removes instructions from the memory, decode, and execute them. It also calls on the ALU whenever necessary. CPUs were traditionally built using ICs but ...

Design of Synchronous Sequential Counters ELEC201 Digital Electronics Partner Name: Objectives The objectives of the laboratory were as follows: Introduction Counters are categorized under Medium Scale Integrated sequential logic circuits. The counter circuits consist of several flip-flops that have been cascaded together and may also have an additional combinational circuit. They are mostly used in application that involve counting where they are applied in either the measurement of time that elapses between two instances that are not known, or the measurement of the frequency of a particular signal.

There are several types of counters such as those given below

- Asynchronous counters - ...

Module 6

Study of Sequential Sequence Detectors ELEC201 Digital Electronics Partner Name: Introduction Circuits whose state transitions are controlled by a clock pulse are called synchronous sequential circuits. Other circuits whose state transitions are not controlled by a clock signal are called asynchronous circuits. This lab aims at equipping students with knowledge on synchronous sequential machines. These are machines designed to solve a problem, which requires the output, to be some specific value after a given sequence of input values has been observed. This problem led to the development of two types of machines in the mid-1950s. These machines ...
