| The 1-bit amplifier processes analogue signals by a 7th-order delta-sigma modulation 1-bit coding circuit which samples at the same sampling frequency of SACD which is 64 fs (2.8224 MHz). The 1-bit signals are then transmitted to a high-speed switching circuit to generate signals to drive speakers. | ||||||||||||||||

| These 1-bit signals are very simple digital data indicating amplitude with a 1 or 0. And the digital data time resolution ability of 0.3543 µs results in the 7th-order modulation 1-bit coding circuit producing a 1-bit signal every 0.3543 µs. The end result is digital data representing an analogue signal with 0 Hz -- 100 kHz frequency range and 120 dB dynamic range. CD, with its 16-bit signal every 22.6757 µs represents an analogue signal with 0 Hz -- 20 kHz frequency range and 96 dB dynamic range. And 192 kHz high-sampling DVD-A's 24-bit signal every 5.2083 µs represents an analogue signal with 0 Hz -- 96 kHz frequency range and 144 dB dynamic range. Comparing sampling times, 1-bit is sampled 64 times faster than CD's (0.3543 µs versus 22.6757 µs) and is 15 times faster than DVD-A's (0.3543 µs versus 5.2083 µs). In fact, 1-bit samples the analogue signal 2,822,400 times per second. 1-bit's high resolution (time resolution ability) creates time accuracy which is essential for natural sound expression. And 1-bit technology with its ultra-high sampling speed makes the faithful reproduction of all sounds in nature possible. * All figures and values used are theoretical. |
