Abstract
Digital audio tape recorders perform significantly better than conventional tape recorders in respect of their frequency response, dynamic range, signal-to-noise ratio, and wow and flutter figures. They also have advantages in terms of their tape size and playing time, and their ability to record additional information as 'sub-codes'. The suitability of DAT recorders as a means for storing ultrasound Doppler signals has been evaluated. The results show that they are an ideal instrument for recording directional Doppler signals, but like conventional tape recorders are not suitable for storing quadrature Doppler signals.Keywords
