FIELD OF THE INVENTION
Our present invention relates to a circuit arrangement for compensating temperature dependent frequency variations of an oscillator of the crystal-controlled type which generates a carrier for the translation of messages by frequency modulation.
BACKGROUND OF THE INVENTION
For the compensation of carrier-frequency fluctuations due to changes in ambient temperature it is customary to use a resistance network including one or more thermistors disposed in the vicinity of the oscillator so as to sense the temperature changes affecting the quartz crystal which acts as frequency-controlling element thereof. A connective voltage emitted by the resistance network is fed to an adjustable impedance, such as a varactor, in circuit with that crystal to counteract the thermal fluctuations in carrier frequency.

本发明涉及的领域
我们目前的发明涉及一种可以修正依赖温度频变的晶控型振荡器的电路装置，该振荡器可以生成一种通过调频转换信息的载体。
本发明的背景
为了修正因周边温度改变而产生起伏的载频，一般的惯用法是使用一个电阻网络，其中包括一个或多个配置在振荡器附近的热敏电阻，以便检测能够影响作为频率控制的水晶体的温度变化。由电阻网络排出的系联电压被传至像变容二极管一样的可调节的阻抗，通过水晶电路以抵消载频的热起伏。
领域的发明
我们目前的发明涉及到电路的安排，补偿随温度变化的频率变化的一振荡器的晶体-控制型生成一个载体，翻译的讯息频率调制。
背景发明
为补偿载波频率的波动变化，由于在常温，这是习惯使用电阻网络，包括一个或多个热敏电阻弃置在附近的振荡器等，以意识的温度变化影响石英晶体作为频率控制的组成部分。一连接排放的电压由电阻网络是美联储可调阻抗，如变容，在电路与晶体，以抗衡的热波动的载波频率。
发明的领域
我们当前发明与晶体控制类型的振荡器，其补偿的温度依赖频率变异的一个电路安排关连由调频引起的一个载体。
发明背景
为载体频率波动的报偿，由于在周围温度上的变化使用抵抗网络包括一个或更多热敏电阻被配置在振荡器附近以便感觉影响作为因此频率控制元素的石英晶体的温度变化是习惯的。 抵抗网络散发的连通性电压哺养对可调整的阻抗，例如一个变容二极管，在电路以那水晶抵制在载波频率的热量波动。
