Effective number of bits (ENOB) is a measure of the real dynamic range of an analog-to-digital converter (ADC), digital-to-analog converter (DAC), or associated circuitry. . Although the resolution of a converter may be specified by the number of bits used to represent the analog value, real circuits however are imperfect and introduce additional noise and distor
An ADC with an intermediate FM stage first uses a voltage-to-frequency converter to produce an oscillating signal with a frequency proportional to the voltage of the input signal, and then uses a frequency counter to convert that frequency into a digital count proportional to the desired signal voltage. Longer integration times allow for higher ...
The unit of measurement is Weighted TeraFLOPS (WT) to specify Adjusted Peak Performance (APP). The weighting factor is 0.3 for non-vector processors and 0.9 for vector processors. For example, a PowerPC 750 running at 800 MHz would be rated at 0.00024 WT due to being able to execute one floating point instruction per cycle and not having a ...
If the DNL of an ADC is smaller than -1, missing codes appear in the transfer function, i.e. there are codes for which there is no input voltage to get the code at the ADC output. If the DNL of a DAC is bigger than 1, the transfer function of the DAC becomes non-monotonic .
The circuit consists of an up-down counter with the comparator controlling the direction of the count. The analog output of the DAC is compared with the analog input. If the input is greater than the DAC output signal, the output of the comparator goes high and the counter is caused to count up. The tracking ADC has the advantage of being simple.
[15] [16] A QUIC working group was established in 2016. [17] In October 2018, the IETF's HTTP and QUIC Working Groups jointly decided to call the HTTP mapping over QUIC "HTTP/3" in advance of making it a worldwide standard. [18] In May 2021, the IETF standardized QUIC in RFC 9000, supported by RFC 8999, RFC 9001 and RFC 9002. [19]
An Application Delivery Controller (ADC) is a type of server that provides a variety of services designed to optimize the distribution of load being handled by backend content servers. An ADC directs web request traffic to optimal data sources in order to remove unnecessary load from web servers.
