how do i calculate bus throughput

trademark

if i have a 33mhz , 33-bit bus ... how do i calculate the throughput

this is for an exam , i know the answer is 132 mbps but surely its not as simple as just using the bits and x by 4

any advice would be gratefully recieved

The PCI bus bandwidth is calculated as follows:

33 MHz × 32 bits = 1,056 Mbs

1,056 Mbs ÷ 8 bits = 132 MBs

Note that it is 132 M bytes per sec not 132 M bits per sec as you said.
