    • A demodulator for an angle modulated signal consists of circuitry particularly adaptable to integrated circuit construction. The various circuit functional groups are adapted to be connected in parallel, rather than serially, across the power source, thereby enabling good performance in systems having low voltage power sources. The angle modulated signal is converted into first and second signals of opposite phase. Also, the angle modulated signal is phase shifted an amount dependent upon the frequency deviation from a center frequency, the first and phase shifted signals are applied to a first OR circuit which provides the largest input signal as its output. The second and phase shifted signals are applied to a second OR circuit which provides the largest input signal as its output. The two OR circuit outputs are low-pass filtered and subtracted to provide the demodulated output.
    • 用于角度调制信号的解调器由特别适用于集成电路结构的电路组成。 各种电路功能组适于在电源上并联连接而不是串联连接,从而在具有低电压电源的系统中实现良好的性能。 角度调制信号被转换成相位相位的第一和第二信号。 此外,角度调制信号相对于与中心频率的频率偏差相关的量,第一和相移信号被施加到提供最大输入信号作为其输出的第一OR电路。 第二和相移信号被施加到提供最大输入信号作为其输出的第二OR电路。 两个OR电路输出被低通滤波并减法以提供解调输出。
