    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Hello Gents,

I am in the phase of designing a Software Defined Radio, and I should
state the (Processing/Computational Requirements) of the
processor/FPGA/DSP to be used.

SDR Parameters:
Operational band: 70-3800MHz
Baseband Bandwidth: 56MHz
ADC/DAC sample rate: 160MHz
ADC/DAC Resolution: 16Bits

Processing/Computational requirements would start with "what do I need
to process, and at what rate?"
The requirement would end up expressing it in MIPS, GigaMACs/s, MB/s,
GHz and/or similar benchmarkable speed metrics.

I would like to know please what is the most accurate way to calculate
that?

Best Regards ,,
