摘要： An audio system includes a processor including an input configured to: receive a baseband audio signal and modulate the baseband audio signal to create a modulated audio signal comprising audio signal frequency components in a first frequency range; clip the modulated audio signal to create a clipped, modulated audio signal the clipped modulated audio signal comprising the audio signal frequency components in the first range and further comprising distortion frequency components outside the first frequency range. The system can further be configured to filter the clipped, modulated audio signal to remove frequency components outside the first frequency to remove distortion components outside that frequency range.

摘要： An SSB transmitter includes a digital-to-digital converter generating first and second real signal components as a function of a complex input signal supplied to the transmitter, and a digital Hilbert transformation module coupled with the digital-to-digital converter and operative to generate first and second transformed signals as a function of the first and second real signal components. The transmitter further includes first and second bit-stream generators operative to generate first and second analog signals as a function of the first and second transformed signals, respectively. The transmitter includes first and second amplifiers. The first amplifier is operative to generate a first amplified signal as a function of the first analog signal. The second amplifier is operative to generate a second amplified signal as a function of the second analog signal. An analog hybrid coupler is connected with the first and second amplifiers and operative to perform an analog Hilbert transformation.

摘要： A wideband phase modulator comprises a multiphase generator, a phase selector, and a phase adjuster. The wideband phase modulator is configured to receive an N-bit digital phase-modulating signal comprising a timed sequence of N-bit phase-modulating words, where N is a positive integer representing the bit resolution of the N-bit digital phase-modulating signal. The multiphase generator generates a plurality of coarse carrier phases, all having the same carrier frequency but each offset in phase relative to the other. The M most significant bits of the N-bit phase-modulating words are used to form M-bit phase select words that control the output phase of the phase selector. The phase adjuster performs a precision rotation operation, whereby a selected coarse carrier phase is adjusted so that the phase of the resulting final precision phase-modulated signal more closely aligns with a desired precision phase.

摘要翻译：宽带相位调制器包括多相发生器，相位选择器和相位调节器。宽带相位调制器被配置为接收包括N位相位调制字的定时序列的N位数字相位调制信号，其中N是表示N位数字相位调制信号的位分辨率的正整数。多相发生器产生多个粗载波相位，它们都具有相同的载波频率，但每相位相对于彼此相位偏移。 N位相位调制字的M个最高有效位用于形成控制相位选择器的输出相位的M位相位选择字。相位调节器执行精密旋转操作，由此调整所选择的粗载波相位，使得所得到的最终精度相位调制信号的相位与期望的精度相位更紧密地对准。
