a timer that resets itself every time the patient’s heart beats. If the heart does not beat on schedule (say‚ within 1.2 seconds)‚ the pacemaker gives a stimulus that causes a heartbeat. You are on the board of directors of a company that makes transistors. Among the many companies with whom you have a contract is one that makes heart pacemakers. Pacemaker technology is in its infancy. When doctors implant a pacemaker‚ the patient’s normal heartbeat is disabled‚ and he or she relies entirely on the

Question 1. Briefly describe Moore law. What are the implications of this law? Are there any practical limitations to Moore law? Moore’s Law is a hypothesis stating that transistor densities on a single chip double every two years. Moore ’s law describes a long-term trend in the history of computing hardware. The number of transistors that can be placed inexpensively on an integrated circuit has doubled approximately every two years. Moore ’s law is a rule of thumb in the computer industry about

In electronics‚ an integrated circuit (also known as IC‚ microcircuit‚ microchip‚ silicon chip‚ or chip) is a miniaturized electronic circuit (consisting mainly of semiconductor devices‚ as well as passive components) that has been manufactured in the surface of a thin substrate of semiconductor material. Integrated circuits are used in almost all electronic equipment in use today and have revolutionized the world of electronics. A hybrid integrated circuit is a miniaturized electronic circuit constructed

INVISIBLE BROKEN WIRE DETECTOR 1 1. INTRODUCTION In our day to day life we are dealing with electricity as well as so many electrical equipments. In this electrical equipment the household appliances play a major role. So the fault occurring with them is also a major problem. Generally the fault seen is the breaking of wire inside the two layer or three layer cables or the short circuit between them. Portable loads such as video cameras‚ halogen flood lights‚ electrical irons‚ hand drill

of the household appliances like TV‚ refrigerator uses stabilizers to supply constant voltage to the appliance in spite of the fluctuations in input voltage. In this‚ we are going to explain the working of a voltage regulator using IC748 and transistors‚ resistors and capacitors. INTRODUCTION In most of the practical situations‚ the output of some systems required to be maintained at a constant level. So a voltage regulator serves the purpose. A voltage regulator is designed to automatically
