CGS-2100 Lecture Notes - Lecture 22: Digital Signal Processor, Technological Convergence, Personal Information Management
Document Summary
Digital defined: digital formats describe signals as long strings of numbers. They can be replicated perfectly as long as you know the sequence of numbers: through analog-to-digital conversion, the incoming analog signal is measured many times per second. The strength of each measurement is recorded as a number. The sequence of numbers together constitutes a digital form of the wave. Digital convergence: digital convergence is the use of a single unifying device to handle media, Smartphone can do almost anything a laptop can do. Cars come with touchscreen displays with many features. Refrigerators come with displays for playing music and showing photos: as digital convergence increases, standards become necessary to make sure that these devices can communicate and work with one another. Telephony: telephony is the use of equipment to provide voice communication over a distance, two digital applications of telephony are smartphones and voice over internet. Smartphones: smartphones illustrate the power of digital convergence:
