Re: [Discuss-gnuradio] difference b/w sample rate and symbols per second

[jason sam]

Sorry for prolonging the discussion but I am a bit confused here.The
sensitivity parameter for Freq Mod block is defined as:

sensitivity = (pi * modulation_index) / samples_per_symbol
where,

modulation_index = deviation / (baud_rate / 2)

So what values should i plug in for samples_per_symbol and baud_rate
in the formulas?
