Um, HUH? (Or was that an attempt at sarcasm? )One disadvantage of AM is that you have to tune the magnifacation up/down on the reciever depending on whether you are moving away from, or towards the sender.
It is not!Single Side Band (SSB) is basically AM with the negative portion chopped off.
Note that the first picture is SSB and the second is AM. That is what I mean, thatIt is not!
An AM signal has an upper RF sideband and a lower RF sideband plus the carrier frequency.
The positive and negative voltage swing of the RF signal still occcurs with SSB but one RF sideband is filtered out. Sometimes the carrier is also removed.
I apologize for not being "technical" enough.one RF sideband is filtered out.
And if you have ever listened to 27.555 mHz, you have probably heard it yourself. Hard to say for sure, because it COULD be all the LOUSY (non-linear, over-driven or improperly tuned) amplifiers on there.If you mean can the bandwidth be wider than the double sideband signal, the answer is yes - if an AM transmitter is overmodulated then additional out-of-band frequencies can be generated.
