KNOCK <channel> [<message>] Sends a NOTICE to an invitation-only <channel> with an optional <message>, requesting an invite. This command is not formally defined by an RFC, but is supported by most [which?] major IRC daemons. Support is indicated in a RPL_ISUPPORT reply (numeric 005) with the KNOCK keyword.
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
Inviting yourself to a channel you have "self invite" access on (+i flag set in ChanServ) Adding a user to an "invite list" for automatic access; Getting a copy of the invite list for a channel; Keeping ChanServ in a channel, so it does not empty and so the invite list is not easily lost; To specify a channel as invite-only:
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 ...
Differential nonlinearity (acronym DNL) is a commonly used measure of performance in digital-to-analog (DAC) and analog-to-digital (ADC) converters. It is a term describing the deviation between two analog values corresponding to adjacent input digital values.
The voltage on the capacitor v is directly proportional to the time interval T and can be measured with an analog-to-digital converter (ADC). The resolution of such a system is in the range of 1 to 10 ps. [12] Although a separate ADC can be used, the ADC step is often integrated into the interpolator.
() is the peak message signal level is the mean message signal level. As SQNR applies to quantized signals, the formulae for SQNR refer to discrete-time digital signals. Instead of (), the digitized signal () will be used.
Here, each group of the same letter represents a 4-bit one-bit error-correcting codeword. The codeword cccc is altered in one bit and can be corrected, but the codeword dddd is altered in three bits, so either it cannot be decoded at all or it might be decoded incorrectly .
