What time constant would be the most effective for cutting out low frequency noise from your SSEP cortical responses? - Answer- Answer: 10 mS SSEP cortical responses are in the typical frequency range of 100-200 Hz. That being said, let's see what time constant would give us a good Low Frequency Filter. Remember LFF filters out everything below the cut off frequency and passes higher frequencies. Formula to know: Cut off Frequency = 1 / Time Constant (tc) 1/.01 s = 100 Hz 10 ms = ...
