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.

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.
