A digital filter can be pictured as a "black box" that accepts a sequence of numbers and emits a new sequence of numbers. In digital audio signal processing applications, such number sequences usually represent sounds. For example, digital filters are used to implement graphic equalizers and other digital audio effects. This book is a gentle introduction to digital filters, including mathematical theory, illustrative examples, some audio applications, and useful software starting points. The theory treatment begins at the high-school level, and covers fundamental concepts in linear systems theory and digital filter analysis. Various "small" digital filters are analyzed as examples, particularly those commonly used in audio applications. Matlab programming examples are emphasized for illustrating the use and development of digital filters in practice.
The long awaited and highly revealing diaries of the politician, diplomat, and socialite (married to Lady Diana Cooper) 'This is a fabulous, jaw-dropping read' SUNDAY TIMES 'Duff Cooper was as close to the action as anyone during the dramatic events of the mid-20th century. He was also comically priapic, committing enough sexual indiscretions to fill a dozen diaries' SUNDAY TELEGRAPH 'Fascinating for two things: their testament to an exhilarating century and their witness to a vanished age of power and privilege ... What a man' OBSERVER Duff Cooper was a first-rate witness of just about every significant event from 1914 to 1950. His diary includes some magnificent set pieces - as a young soldier at the end of WWI, as a politician during the General Strike of 1926, as King Edward VIII's friend at the time of the Abdication, and from Paris after the liberation in 1944, when he became British ambassador. If Duff Cooper's name has dimmed in the 50 years since his death, publication of these diaries will bring him to the fore once again. His family have long resisted publication - indeed Duff Cooper's nephew, the publisher Rupert Hart-Davis, was so shocked by the sexual revelations that he suggested to John Julius Norwich that it might be best for all concerned if they were burnt. Now, superbly edited by John Julius Norwich, who familial link ensures all kinds of additional information as footnotes, these diaries join the ranks.
