Audio Power Amplifier Design

Audio Power Amplifier Design

This is the essential book reference for amplifier designers. Douglas Self covers all the design issues of noise distortion power supply rejection protection reliability and layout. He describes advanced forms of compensation that give dramatically lower distortion. This edition is much expanded and packed with new information. It is a must-have for audio power amplifier professionals and audiophiles amateur constructors and anyone with intellectual curiosity about the struggle towards technical excellence. New to the sixth edition: The characteristics of the audio signal The principles of distortion Feedback intermodulation distortion Non-switching output stages VAS distortion explained Push-pull VAS configurations Output-inclusive compensation In addition five amplifier design examples that illustrate important design principles are examined and measured in detail. These can be straightforwardly adapted to specific requirements. This new edition also includes a wealth of material on the XD crossover-displacement principle (invented by the author and in use by Cambridge Audio) four-stage amplifier architectures error correction current-mirrors power transistors with internal sensing diodes amplifier bridging input-stage-common-mode distortion amplifier stability output stages with gain inrush current suppression DC servo design thermal protection cooling fan control advanced line input stages testing and safety infrared remote control signal activation 12V trigger control the history of solid-state amplifiers and much more. Simple procedures for heatsinking and power supply design are given. | Audio Power Amplifier Design

Scientific and Medical Knowledge Production 1796-1918 Experiment Expertise Experience

Scientific and Medical Knowledge Production 1796-1918 Experiment Expertise Experience

This collection pieces together a wealth of material in order to get inside the experience of scientific practice in the long nineteenth century. It aims to reach or perhaps to facilitate an understanding of the ways in which the value of scientific knowledge was produced lived and challenged. The new turn to the history of experience suggests a logic to the compilation of material that is completely original: the sources are not selected according to the historical success of an idea or experiment but for the ways in which scientific endeavour loaded knowledge claims with political or moral value coupled with attendant practical justifications. Thus ‘bad ideas’ sit alongside ‘good’; now discountenanced practices take their place among the revered. In sum they reveal an experimental culture that was not merely orientated toward cold knowledge or intellectual output but defined by shifting sets of affective practices and procedures and the making of expertise out of the lived experience of doing science. | Scientific and Medical Knowledge Production 1796-1918 Experiment Expertise Experience
