Pump up the volume
‘MP3 players are very popular and are ideally suited for individual listening. Sometimes however it is useful to amplify sound so that the device can be listened to without the restriction of headphones or a small group of people can listen to it together.’
The above is a typical context taken from a GCSE Short Course specification. Your task is to design and manufacture a prototype product in response to this context that incorporates the given amplifier circuit. CAD/CAM is to be used extensively in the development of your prototype. This will be a corporate 'freebie' used to promote a high speed commuter rail network.
