With the figure you showed isn't really what is transmitted in SSB. Rather, it is a rectified sin wave, such that half of it is shown at 0, and the other half shown above. As sound doesn't really …

2016年5月9日 · I'm trying to learn about how SSB modulation works. My current understanding from reading and looking at spectrum plots from SDR software is that the sound is modulated …

2016年11月15日 · Side bands are a natural result of the mixing of two or more electro-magnetic wave-forms, and and SSB is the use of one of those wave-forms to transmit information. In …

2020年8月5日 · $\begingroup$ Thanks Phil, the main points i get from your answer is that a square wave is composed of many sine waves at every odd harmonic and that you can turn a …

2013年10月26日 · SSB has no carrier, and the transmitter does not transmit anything when the operator is not speaking. There is no way to transmit the presence of silence to the receiver. …

2022年12月31日 · So if SSB were a black-box problem, the answer is, an audio signal drives a radio frequency signal off of its "base" or "center" frequency, by whatever the audio frequency …

2013年11月19日 · Mostly, EM propagation is linear, so the differences in modulation have little effect on how the wave propagate. However, if you expand propagation to include the …

2023年6月27日 · The conventional AM, SSB, CW, and FM then the various Data modes like RTTY, PSK, and a seeming myriad of others. Ham radio offers such esoteric activities as …

Normally, SSB filters are at higher frequencies, say above 3-4 MHz, for technical reasons (design characteristics of the crystals). That said, have a look at using your computer as filter. There …

2020年4月23日 · In addition to the "filter method" described earlier, SSB can be generated by the "phasing method." As such, it is a special case of quadrature amplitude modulation (QAM). …
