A first analog input signal is converted into a plurality of second analog signals having different levels respectively. The second analog signals are inputted into respective analog-to-digital converters. Values of output signals from the respective converters are adjusted in accordance with the values...
An analog-to-digital converter for converting a multitude of analog input signals into a corresponding multitude of digital signals comprises a series arrangement of an analog multiplexer (2), an oversampling sigma-delta modulator (8), a decimator-cum-low-pass filter (10), a digital demultiplexer...
The present invention relates to a converting device for converting an analog input signal Vin into a digital output signal OUT, whose gain is equal to the ratio between the values of the output and input signals, comprising: a resistor ladder LAD intended to generate reference voltages, and a...
Multi-stage analog-to-digital converting device A video signal converting device is capable of converting an analog composite signal into a proper digital signal with a small delay even if the analog composite signal contains much jitter. The video signal converting device has a sampl... K Suzuki...
The system consists of a video module (30) and a number of audio modules (40). The analog video signal (31) is converted (32) to digital form. The audio inputs (41) are each fed to analog to digital converters (42) in the audio modules. All the digital audio signals are chained ...
Apparatus for a telecommunication system having subscriber stations constructed to send and receive analog signals which are communicated from one station to the other by means of digital signals is described. Each subscriber station is equipped with a converter for converting received digital signals int...
The advantage of this invention is that users will be able to quickly, easily, and inexpensively convert a standard dental x-ray viewer into analog and/or digital x-ray image viewing systems, utilizing computer or video monitors. The camera chassis with CCD video board camera is mounted on ...
A floating-point digital-to-analog converting system which includes a mantissa digital-to-analog converter (DAC) and an exponent DAC. Normally, the mantissa DAC has a digital-to-analog converting accuracy higher than that of the exponent DAC because of differences in their construction. Hence, as...
We conclude that the noisy-bit method, combined with the standard 256 luminance levels, is perceptually equivalent to an analog display with a continuous luminance intensity resolution when the spatiotemporal resolution is high enough that the noise becomes negligible (which is easily attainable with ...
