classes of hardware that the modern engineer will use, such as loud-

signal processors. Special at ten tion is given to digital techniques fo r
s y s tem control and to audio signal analys i s. Se ction 3 deals with the
basics of sys tem design, from concept to final realizat i o n . It cove r s
topics such as basic sys tem type and speech inte l l i g i b i l i t y, s i te survey,
