发明名称 METHOD FOR THE TRANSMISSION OF INFORMATION, IN WHICH THE SIGNALS ARE CODED BY WAY OF THE MAGNITUDE OF THE AMPLITUDES OF THE HALF-WAVES OR PERIODS OF A SINUS- WAVE ALTERNATING CURRENT
摘要 <p>: Method for the transmission of information, in which the signals are coded by way of the magnitude of the amplitudes of the half-waves or periods of a sinus-wave alternating current Due to pulse amplitude modulation (PAM) there is an unwanted signal being undesirably strong and a broadening of the frequency band as a result of the pulses. In the case of digital binary-coding of signals with half-waves or periods of an alternating current and the code elements having small and large amplitude values, high frequencies are required. In the present invention, the samples of the pulse amplitude modulation of signals ranging from single polar/binary to continuous are being coded by half-waves or periods of an alternating current, also providing alternating currents of a lower frequency with predetermined mutual phase shifting for the samples. Due to these measures the aforementioned shortcomings are avioded.</p>
