Designing and presenting stimuli with TDT hardware
With the TDT system we can create and control sound stimuli in realtime. Stimulus parameters such as loudness, duration and onset timing can be controlled using the circuit components of the RPvdsex software. To create a stimulus, a relevant circuit has to be loaded onto the RP2 Realtime Processing unit. These files are called .rcx/.rpx files and can be found on the C:\MATLAB\experiment\RPvdsex drive on the experimental pc in the Biophysics lab.
Let's start with an example of gaussian white noise to see what is needed to present a stimulus.
