摘要： A double sideband suppressed carrier modulator apparatus for combining two serrodyne (i.e., single sideband) modulators to achieve double sideband, suppressed carrier modulation. An RF input signal is divided into two carrier signals which are 90 degrees out of phase and applied to the serrodyne modulator units. The modulated signals from the modulators are combined in a 90 degree power divider to provide a double sideband suppressed carrier modulated output signal.

摘要： The modulating device reduces the number of electronic functions required for generating an SSB signal which is subjected to SSB peak-limiting in a transmitter which is selectively operable either on the upper channel or on the lower channel. By means of a mixer, the signal delivered by the peak-limiter is mixed with a signal whose frequency is double that of the local oscillator. By filtering the signal thus obtained by means of the filter which is symmetrical with the filter employed for carrying out SSB modulation, the signal to be transmitted on one of the channels is thus obtained. The signal to be transmitted on the other channel is obtained by reversing the position of the two filters.
摘要翻译：调制装置减少了在发射机中经受SSB峰值限制所需的用于产生SSB信号所需的电子功能数量，该发射机可选择性地在上部信道或下部信道上操作。通过混频器，由峰值限制器传递的信号与频率为本地振荡器频率的两倍的信号混合。通过利用与用于进行SSB调制的滤波器对称的滤波器对由此获得的信号进行滤波，从而获得在其中一个信道上传输的信号。通过反转两个滤波器的位置来获得要在另一个通道上发送的信号。

摘要： A single-sideband modulator and demodulator are realized by using reference time functions. The desired modulated or demodulated signals are generated by modulating and filtering a train of pulses of constant amplitude to develop a reference time function which, in turn, is scaled in accordance with sampled values of an applied baseband or modulated signal.
