Digital signal processing Digital signal processing Digital signal processing (DSP) is the mathematical manipulation of an information signal to modify or improve it in some way. It is characterized by the representation of discrete time‚ discrete frequency‚ or other discrete domain signals by a sequence of numbers or symbols and the processing of these signals. The goal of DSP is usually to measure‚ filter and/or compress continuous real-world analog signals. The first step is usually to

Advantages of Digital Circuits Name: Instructor: Institution: Introduction Digital circuits are circuits that use signals in digital form instead of analog forms. One distinctive feature of a digital signal is that it assumes discrete values‚ most of the time two values. A digital signal takes time to change from one value to another‚ and assumes intermediate values during transmission (Verma). Steady values are slightly inaccurate. Voltages

American International School April 29‚ 2011 The Digital Camera Have you ever wondered who created a camera that can actually capture a moment in time and saves it inside the camera‚ and that camera can transfer the image to the computer‚ while being capable of editing the image on the camera itself? I think the digital camera is very important because it takes photography to a whole new level. In this essay‚ I will explore who invented the digital camera‚ where that person got their idea‚ and

PCM CODING/COMPANDING Q1. a)i) The process of quantisation introduces an error or noise component into the quantised signal. Derive an equation for the mean-squared quantisation error in terms of the quantization interval ‘a’. ii) Hence show that the peak signal-to-quantisation noise ratio (SQNR) is SQNR = ( 6n + 4.8 ) dB Where 2 n is the number of quantisation levels. b)i) Linear quantisation is used prior to binary PCM encoding of an analogue baseband signal which has

The digital world‚ especially its omnipresence and highly structured environment‚ has introduced a new sort of rhetoric which holds a significant effect on identity. Digital rhetoric theory has come about as a result of communication occurring via various electric formats (Plessis 2013 p. 2). The Internet functions as a source which promotes “rethinking of identity as anonymous‚ fluid‚ and unfixed” because of its collaborative nature (Hess 2014 p. 3). Users are always interacting with the readily

Using a Peer-to-peer file-sharing program integrated in websites like 4shared.com and MEGAUPLOAD.com. As having friends in the Music Industry‚ I do believe people should not break the copyright law and instead pay the music artists for their work.
