A noise reduction algorithm used in speech signal processes which is referred to as LMS adaptive noise reduction, is also designed to reduce wide-band noise but improve signal to noise Ratio.

So the tape recorder which adopts this magnetic head can be used for wide band direct replay and makes signal-noise ratio improvement, it is an ideal playback head.

Based on the model, the BER Bit Error Ratio performance is analyzed for narrow-band modulation and wide-band spread -spectrum modulation of coherent PSK Phase Shift Key...
