Micro-processor, Micro-controller and PeripheralsAmit Kumer Podder The document describes the evolution of microprocessors from the Intel 4004 in 1969 to the Intel Core 2/Quad in 2006-2007. It provides details on the clock speed, number of transistors, register size, and other specifications for each microprocessor model. The document also includes slides on a session on microprocessors, microcontrollers, and peripherals that discuss topics like number representation, binary to hexadecimal conversion, and the working of an 8085 microprocessor kit.
Lecture on wire splicing and termination
Lecture on wire splicing and terminationAmit Kumer Podder The document outlines wire splicing and termination techniques, detailing the importance of splicing in creating electrical connections from longer wire lengths. It describes various splicing methods, such as the Western Union splice, married joint, and pigtail joint, along with their application in specific scenarios. The lecture emphasizes proper termination practices to prevent short circuits and ensure safe electrical installations.
