Practical Wireless has always been a ‘doing’ magazine with the accent on the practical, constructional side of Amateur Radio. Renowned for providing good homebrew projects, PW gives full assembly instructions for all types of old and new ideas ranging from the absolute beginner projects in our series called ‘Radio Basics’ to projects for the more advanced Radio Amateur, such as in our series: Carrying On The Practical Way.
The implementation of electronic circuit designs to perform conversions of sound/pressure wave signals to electrical signals, or vice versa, is known as audio electronics. Electronic circuits considered to be part of audio electronics may also be designed to perform specific signal processing operations in order to make specific changes to the signal while it is in electrical form. Furthermore, audio signals can be generated synthetically by generating electric signals from electronic devices. Until the development of digital technologies, audio electronics were traditionally designed using analogue electric circuit techniques. Furthermore, due to their compatible digital nature, digital signals can be manipulated by computer software in much the same way that audio electronic devices can. Both analogue and digital design formats are still used today, and which one is used depends largely on the application. Receive Free Audio & Electronics Magazines.
