Hello the list... Has anyone attempted to do a Weaver modulator to generate a baseband ssb signal in Spectrum Laboratory? Looks like it should be possible... -- 73 Warren K2ORS WD2XGJ WD2XSH/23 WE2XE
Hi Warren, It's not strictly the Weaver method but there is an SSB 'up-converter' with I and Q outputs in SL. It actually uses a forward and inverse FFT, and cos^2 windowing (with 50 percent overlap)
That seems a very convoluted (!!) way of doing what is actually quite a simple process. Input low-pass filter, I/Q mix with a centre tone, low pass filter the output- and there's the baseband signal
Well the main purpose of the filter is filtering. Letting it produce an I/Q output is more or less a by-product, and it works extremely well. Am 14.04.2016 um 19:54 schrieb Andy Talbot: That seems a
It's not a Weaver modulator, but G3PLX's SDR transmitter that generates I/Q outputs from a soundcard and also, in a very clever way, allows FM and AM to be generated when no DC component is present.
Wolf, Andy, Many thanks for the information! Yes a single chip ssb baseband generator would be very cool indeed! 73 Warren -- 73 Warren K2ORS WD2XGJ WD2XSH/23 WE2XEB/2 WE2XGR/1
