RPSGT Exam Instrumentation/ Waveforms Questions with correct Answers 2023 According to the principles of differential amplification, electrical interference can best be prevented if The impedances of input elecrodes are similar During a recording, the technologist notices that the HFF on an EOG channel is set at 15Hz. Which of the following is correct? Rapid eye movement signals will be attenuated G1 receives an input voltage of -100uv while G2 simultaneously receives -50uv. The...

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 = ...
