Learn to exploit reasonably cheap and available elements to acquire cutting-edge functionality in all of the very important parameters of noise, distortion, crosstalk etc. With considerable insurance of preamplifiers and mixers and a brand new bankruptcy on headphone amplifiers, this functional guide presents an in depth repertoire of circuits that may be prepare to make nearly any form of audio system.
A source packed filled with worthwhile info, with nearly each web page revealing nuggets of specialised wisdom now not stumbled on somewhere else. crucial issues of conception that endure on functional functionality are lucidly and carefully defined, with the maths stored to a relative minimal. Douglas' heritage in layout for manufacture guarantees he retains a cautious eye at the fee of items. contains a bankruptcy on power-supplies, packed with functional how one can hold either the ripple and the associated fee down, exhibiting tips on how to energy everything.
Douglas wears his studying frivolously, and this ebook positive factors the enticing prose kind ordinary to readers of his different books. you are going to study why mercury cables are usually not a good suggestion, the pitfalls of plating gold on copper, and what prices from superstar Trek need to do with PCB design.
Learn how to:
- make amplifiers with it seems that impossibly low noise
- design discrete circuitry that may deal with huge, immense signs with vanishingly low distortion
- use humble low-gain transistors to make an amplifier with an enter impedance of greater than 50 Megohms
- transform the functionality of low-cost-opamps, the way to make filters with very low noise and distortion
- make tremendously exact quantity controls
- make a tremendous number of audio equalisers
- make magnetic cartridge preamplifiers that experience noise so low it truly is constrained by way of easy physics
- sum, change, clip, compress, and course audio signals
The moment variation is increased all through (with extra details on new ADCs and DACs, microcontrollers, extra assurance of discrete op amp layout, and plenty of different topics), and features a thoroughly new bankruptcy on headphone amplifiers.
