Description

Известны способы дифференцировани  и Нитегрирозани  электрических сигналов с помощью мостов, работающих на одной частоте. Известен также мост переменного тока, в плечи которого включены нелинейные сопротивлени .Methods are known for differentiating and filing electrical signals using bridges operating on the same frequency. Also known is an ac bridge, the shoulders of which include nonlinear impedances.

Предлагаемый способ позвол ет дифференцировать (интегрировать ) огибающую модулированного переменного тока с амплитудной модул цией в щироком диапазоне изменени  частоты несущей с помощью сбалансированного моста, в плечи которого включены нелинейные сопротивлени , имеющие одинаковые статические и разлнчные динамические характеристики. В качестве таких сопротивлений могут быть использованы термосопротивлени .The proposed method allows to differentiate (integrate) the envelope of the modulated alternating current with amplitude modulation in a wide range of variation of the carrier frequency using a balanced bridge, the shoulders of which include nonlinear resistances having the same static and different dynamic characteristics. Thermal resistances can be used as such resistances.

Дл  дифференцировани  термосопротивлени  включают в соседние плечи моста, дл  интегрировани  - в противоположные; в остальные плечи включены активные линейные сопротивлени . На одну диагональ моста подаетс  входной сигнал, с другой диагонали снимают выходной сигнал. Величины сопротивлений нелинейных элементов в установившемс  /режиме одинакрвы и мостнаходитс  в .равновесии: При изменении огибающей входного сигнала мост в переходном режиме разбалансируетс , вследствие разности посто нных времени термосопротивлений . To differentiate, thermistors are included in the adjacent shoulders of the bridge, for integration into opposite ones; active linear resistances are included in the remaining arms. An input signal is applied to one bridge diagonal, an output signal is removed from the other diagonal. The magnitudes of the resistances of nonlinear elements in the steady state / mode are equal and the bridge is in equilibrium: When the input signal envelope changes, the bridge in the transient mode becomes unbalanced due to the difference in the constant time of the thermal resistances.

Предложенным способом можно производить дифференцирование ИЛИ-интегрированпе «огибающей тока с амплитудной либо щиротно-импульсной модул цией.The proposed method can be used to differentiate an OR-integrated "current envelope with amplitude or pulse-width modulation.

Предмет изобретени Subject invention

Способ дифференцировани  (интегрировани ) огибающей сигналов с амплитудной, а также огибающей сигналов с широтно-имлульсной. модул цией , отличающийс  тем, что входной сигнал подают в диагональ сбалансированного моста, в соседние (противоположные) плечи которого включены нелинейные сопротивлени  с одинаковыми статическими и различными динамическими характеристиками (например, термосопротивлени ), и выходной сигнал снимают с другой диагонали моста.The method of differentiation (integration) of the envelope of signals from the amplitude, as well as the envelope of signals from the width-impulse. modulation, characterized in that the input signal is fed to the diagonal of a balanced bridge, the adjacent (opposite) arms of which include nonlinear resistances with the same static and different dynamic characteristics (for example, thermal resistance), and the output signal is removed from another diagonal of the bridge.
