Re: [Discuss-gnuradio] bit rate of the random source

[Josh Blum]

The bit-rate or sample-rate is determined by the first block in the flow 
graph that conceptually treats the stream as having a "rate".

The signal source block outputs periodic signals so it must have the 
concept of a sample rate. However, a random source, noise source, or a 
constant source does not.

If you were to connect the output of the random source to a scope or fft 
display, the display would need to know the sample rate in order to 
scale its axis. And therefore the concept of bit-rate or sample-rate 
becomes defined by the parameters of the graphical display.
