How would i convert a bandwidth of say 30kHz to bps if I only know the number of bits per sample (4)? (and I was using a two chanel system). I am assuming it is simply 30KHz * 2 * 4 but this may be wrong

You haven't mentioned what the sampling rate is. According to the Nyquist Rate, you'll need to sample at twice the analog bandwidth to achieve alias-free sampling.

So assuming you want 60 kHz sampling, your total data rate will be:

60 kSamples/sec * 2 channels * 4 bits per sample = 480 kbps.

    \$\begingroup\$ I think you're reading the question as if the OP is sampling the signal and want to work out the bit-rate of the result. But my interpretation of the question is that the OP wants to know what the potential data bit-rate would be using that 30kHz as a communication channel. \$\endgroup\$ – brhans Jun 5 '19 at 14:18
