Subject: Dumped Integrator gen. Подскажите пожалуйста, что такое Dumped Integrator?Спасибо. |
|
выброшенный в помойку интегратор за отсутствием контекста большего... |

Вот контекст Hybrid Microcircuit Description: Dumped Integrator, Digital Part Number: 585R927 Package: Hermetic, Butterfly, 1.0 x 2.0 in seal; 1.75 x 0.8 in. substrate Interconnections: Bimetal 212; single metal 58 Active Components: 4-10581; 1-10579; 3-10576 Passive Components: 4-Ceramic chip capacitors, 10% stress ratio, 1000 pf 8-Chip resistors Environment: AUF; 80° C package temperature screened to MIL-STD-883, Method 5008, irQ = 1.0 Помогло? |

tumanov Пардон, не думала, что за живое задену |

Абсолютно не задели... смайлики было лень ставить... возможно, речь идет об "integrate-and-dump integrator" |

The integrate-and-dump processor circuit detects positive or negative-going edges which exceed the ±3V differential threshold. The edge detection causes an integration circuit to integrate the input voltage for a period of 5 μ sec. The output of the integrator is sampled (timing is derived from the edge detector) at the end of the integration period. If it is above zero voltage, a ONE is declared; if it is below zero voltage, a ZERO is declared. |

tumanov Супер а по-русски-то как? |

"the integrator is dumped (meaning that the output is reset to 0)" http://dsp.stackexchange.com/questions/8648/integrator-and-the-multiplier-in-the-optimal-binary-detector |

чуть расширю цитату из документа со ссылки The integrator that you are using is really what is called an integrate-and-dump correlator. The input is integrated over intervals of time [(n−1)T,nT). Just before the end of the integration period, at time nT−−, the integrator output is sampled and the sample value is what is used in the threshold device. Following the sampling at nT−−, the integrator is dumped (meaning that the output is reset to 0) at time nT−, and the integrator is restarted at t=nT for the next data bit from nT to (n+1)T . Note that there is what computer engineers call a critical race involved: the circuit designer has to make absolutely sure that the sample signal arrives at the integrator before the dump signal. Getting this wrong can be a fireable offense. With the integrate-and-dump correlator working as described above, |

Напишу "интегратор со сбросом" Erdferkel, интегратор сбрасывается, то есть его выход устанавливается в ноль, похоже на интегратор со сбросом. Спасибо всем большое! |
| . . то есть его выходНОЙ СИГНАЛ |
