Microprocessor-controlled signal-to-noise ratio measurement system for speech codes

Engineers occupied in the development of hardware coder-decoder pairs (codecs) need an objective performance measure. Such a measure is the mean-square error (MSE). For complicated signals, such as speech signals, the error signal e(t) = S i (t) − s 0 (t) is hard to obtain. The reason for this is th...
