Comparison Of -90Db, 1Khz Sine Waves: Bit Expansion On Vs. Off; Comparison Of Frequency Spectra: Range Expansion On Vs. Off - JVC RX-D702 Technical Manual

CC Converter CC Converter
The figure shows the actual measured
waveform of a bit-expanded -90dB
sinusoidal signal.
The figure shows the frequency spectra of a music signal with the range expansion on
and off. With the expansion off, the level is sharply reduced beyond 22kHz. But with
the expansion on, the level is naturally extended beyond 22kHz and higher.
