Analysis of simple digital circuits means to determine how the circuit behaves, which is represented for its truth table. So, with this aim in mind, lets organise the analysis step by step (as explained in Unit 1. 3 ) : For instance, here you are the circuit from EX1A`s Fig. 2b (NOTE: The circuits in Fig. 2 are only samples of simple comb

inational circuits using logic gates. Your instructor may change them for other similar ones. In this way, your aim is to analyse the circuit proposed in classroom, see your class group agenda ( 3GM1 or 3GT3 ): Analysing an example from a book: Floyd, 10e, Chapter 5. Visit the book`s webpage and study the slides which are available. Be aware that your instructor may have changed this design by another similar, please check your particular class group agenda ( 3GM1 or 3GT3 ):. Rewrite the circuit using logic gates transformations so that it can be easily captured in Proteus-ISIS. Insert your circuit inside a subcircuit box taking the previous example as the starting point. Obtain the circuit`s truth table: continue the transformation adding the missing variables so that the products are transformed into minterns (sum of minterms), or the sums are transformed into maxterms (product of maxterms). In order to check that the Lattice software is correctly installed in your portable computer or the lab, just run the demonstration project available in Unit 1. 5A ( here ), which is an Hexadecimal to BCD decoder. It it synthesised for a GAL22V10 sPLD device (see Unit 1. 6 ). The project is composed of different files, a mix of schematics and VHDL. So, the idea is clear: let`s try to use VHDL instead of schematics of logic circuits. So, from now, all your projects are going to be VHDL-only, in a way that we`ll let the system draw the...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
