Re: [Discuss-gnuradio] A simple analogue question.

If I have two signals entering a receiver, both with a power of 0 dBm, what would be the total input power seen by the receiver? Is it 3 dBm or 6 dBm? Anywhere between 6dBm and -174 + 10*log() dBm, assuming a 50-Ohm system at room temperature. JD 'correlation' B. -- LART. 250 MIPS under one

Re: [Discuss-gnuradio] CIC decimator in software

2011-04-17 Thread J.D. Bakker
I'm looking for opinions about whether doing a single-stage, N=2 decimator in software is practical for sample rates of ~100Msps. Assume reasonably-modern X86-64 hardware, and R=[2..500]. Assuming you can get the data into the processor fast enough, I expect you will. (As a reference poin
