Audio Signal Processing

AIM - Record Audio , Add and Remove Noise and play back audio. To design and implement the Embedded System centred on an Altera DE2-115 Development Board. The project should be based on a Verilog HDL implementation. Available Hardware In addition to the DE2-115 board, the following hardware devices are available. If you wish to do a project requiring hardware support but don’t see the required peripherals on the list, please discuss with the lecturer as soon as possible. • Ultrasonic range finders XL-MaxSonar-EZ/AE MB1200 • Microphones, Speakers • Infrared remote controls • PAL Camera device (limited numbers) • PS/2 keyboard (limited numbers) Note that the audio peripherals on the board may be used as general purpose analogue I/O, within the voltage and bandwidth limitations specified by the codec device. In addition, the VGA DACs may be used as general purpose high speed, high resolution Digital to Analogue converters.
