can someone explain me the third method of SSB AM signal generation which is also known as the Weaver's method.

i understand the other two methods which are the filter method and the phasing method. the main drawback of the filter method is that it has a filter which should have an ideal behaviour. and the drawback of the phasing method is that a 100% phase shifting circuit is not realizable in real life circuits.

but the third method uses both filters and phase shifter circuits. so it should have the disadvantages of both the other two methods. am i right????

Sam - you might find what you need in the ARRL Handbook or similar amateur radio publications. Check the ARRL website - may be an article or two on SSB.

okay thanx stevez. actually i have the ARRL handbook for Radio Amatuers 2001. but this method is not explained in it. i have found a couple of sites that do explain it a little bit. but i was just wondering if someone on electro tech knows about it so i can discuss with him.

The Weaver does use phase shift and filters but they are generally easier to implement than the other two methods. The phase shift is just required for two constant frequencies, not a range of frequencies such as in the phasing method, and the two filters are simple, they just have to be matched.

True, but the question wasn't completely answered before and someone else requested a further explanation now.

Not exactly, a further explaination was requested eight months ago.
