Audio DSP Course (6)
Part 6: Digital signal generator
An audio signal generator for lab use needs to have two basic features. First, it must be able to generate low-distortion sine waves with an adjustable frequency and amplitude to allow measurement of the frequency response and distortion factors of audio equipment; and second, it must be able to generate low-pass and band-pass noise signals to help characterise electro-acoustic transducers. A DSP makes the ideal basis for such a device.
