Description
(Ц) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ КОЭФФИЦИЕНТА НЕЛИНЕЙНЫХ ИСКАЖЕНИЙ(C) DEVICE FOR MEASURING THE NONLINEAR DISTRICT RATIO
ИзоБретение относитс к радиоизмерени м .INVENTION refers to radio measurements.
Известно устройство дл измерени коэффициента нелинейных искажений, содержащее режекторный фильтр, детектор эффективных значений, полосовой фильтр, вход которого подключен через основной широкополосный регулируемый усилитель к первому входу сравнивающего блока, второй вход которого соединен с выходом источника опорного напр жени , а выход сравнивающего блока подключен ко входу усилител посто нного тока l .A device for measuring the nonlinear distortion coefficient is known, which contains a notch filter, an effective value detector, a band-pass filter whose input is connected via a main wideband adjustable amplifier to the first input of a comparison unit, the second input of which is connected to the output of a reference voltage source, and the output of the comparison unit is connected DC amplifier input l.
Однако оно не имеет достаточной точности.However, it does not have sufficient accuracy.
Наиболее близким по технической сущности к изобретению вл етс уст;ройство , содержащее режекторный фильтр, вход которого подключен к входу полосового фильтра, ёыход которого подключен к первому входу широполосного регулируемого усилител , второй вход второго широкополосного усилител через усилитель I разбаланса соединен с выходом сравнивающего блока, детектор эффективных значений и источник опорного напр жени 2.The closest in technical essence to the invention is a device containing a notch filter, whose input is connected to the input of a bandpass filter, whose output is connected to the first input of a wideband adjustable amplifier, the second input of the second wideband amplifier is connected to the output of the unbalance amplifier I, effective value detector and reference voltage source 2.
Недостатком данного устройства вл етс .относительно высока погрешность при измерении малых значений нелинейных искажений.The disadvantage of this device is a relatively high error when measuring small values of nonlinear distortion.
Цель изобретени - уменьшение по10 грешности при измерении малых значений нелинейных искажений.The purpose of the invention is to reduce by 10 errors when measuring small values of nonlinear distortion.
Поставленна цеЛь достигаетс тем, что в устройство дл измерени коэффициента- нелинейных искажений, The goal is achieved by the fact that in the device for measuring the coefficient of non-linear distortion,
