The eSOC II Board As mentioned in Lecture 3 and the textbook‚ most logic circuits today are built using programmable logic devices (PLDs). These devices allow circuits to be built directly onto single chips‚ without the need for interconnection of separate‚ single purpose ICs. The eSOC II (electronic System-on-a-Chip) board is designed to allow a direct interface between the Quartus II software and the Altera Cyclone II EP2C8 FPGA. The board provides an interface to the chip‚ along with supporting

Superposition theorem is a way to determine currents and voltages in a linear circuit that has multiple sources by taking one source at a time. the current in any given branch of a multiple-source linear circuit can be found by determining the currents in that particular branch produced by each source acting alone‚ with

“Terrorism must be decontextualised” Richard Perle‚ former chairman of the Defense Policy Board I. INTRODUCTION One can say that two occurrences in contemporary history exposed to the bright light internal contradictions of American policy: the real terrorist threat launched for the wide audience on September‚ 11‚ and the biggest ever economical crisis of 2008 and – as analysts predict – of some years after. From these two turning points in Western world history the first one‚ ‘the 9/11‘‚ as

ECE348 Circuit Debugging Tips These guidelines may be useful to you if your circuits are not working as planned: Check the Microcontroller Control Register Settings Sometimes you have to configure multiple control settings before you can enable a pin for a particular purpose (input‚ output‚ A/D conversion‚ etc). Section 2.3.2 of the MCU datasheet describes the control registers related to various ports. Sometimes you may have to look in other parts of the datasheet (for example‚ the A/D section)

a Simple Temperature Display Circuit using LCD ( Liquid Crystal Display ). For Heat Sensor we have used IC LM35 (Precision Centigrade Temperature Sensors ) whose Output voltage is linearly proportional to the Celsius (Centigrade) temperature. Output of LM35 IC is 10mv/degree centigrade for eg if temperature is 35 degree then the output of sensor will be 350mv or 0.35V For working with LCD it is necessary to have Microprocessor. We have used Arduino Controller Board which is AN OPEN-SOURCE ELECTRONICS

Integrated circuit design‚ or IC design‚ is a subset of electrical engineering and computer engineering‚ encompassing the particular logic and circuit design techniques required to design integrated circuits‚ or ICs. ICs consist of miniaturized electronic components built into an electrical network on a monolithic semiconductor substrate by photolithography. IC design can be divided into the broad categories of digital and analog IC design. Digital IC design is to produce components such as microprocessors

Subqueries and derived tables can add great versatility to SQL statements‚ cut down complexity‚ but can occasionally be a curse when their effect on performance is poorly understood. Surely everyone understands the various types of subqueries and how they are used? If you felt a twinge of doubt‚ here is Rob Sheldon’s easy guide to the subject. ew elements within a Transact-SQL statement are as versatile as the subquery. A subquery—also referred to as an inner query or inner select—is a SELECT

Euler and Hamiltonian Circuits As I type this sentence millions of students all over the country are in their math class either a) struggling to open their eyelids or b) tapping their fingers due to boredom and impatience. They have all failed to understand how the topic would later come of use. Although mathematics may seem to be “unnecessary” it teaches our brains to strategize‚ and think differently through the use of trial and error and problem solving. Most individuals consider mathematics

Fire alarm circuit ABSTRACT Here is a simple fire alarm circuit based on a Light Dependent Resistor (LDR) and lamp pair for sensing the fire. The alarm works by sensing the smoke produced during fire. The circuit produces an audible alarm when the fire breaks out with smoke. When there is no smoke the light from the bulb will be directly falling on the LDR. The LDR resistance will be low and so the voltage across it (below 0.6V). The transistor will be OFF and nothing happens. When there is sufficient
