Question

1.) You want to send a "square wave" pulse signal at a frequency of 60 Hz. What characteristics would this signal have?

2.) You want to set up a flicker fusion stimulus with a duty cycle of 50%. Lets say you want to set up a stimulus that is a total of 2 seconds long with a frequency of 1 Hz, 10 Hz, 20 Hz, 40 Hz, 60 Hz, 80 Hz, and 100 Hz. How do you do that? What are your settings within the stimulator window of your recording software for stimulus duration (in milliseconds), number of repeats, and frequency (in Hz)? Match the desired effect (left column) with the relevant setting (right column).

QUESTION 1 You want to send a "square wave" pulse signal at a frequency of 60 Hz. What characteristics would this signal have? If the signal has a duty cycle of 50%, then the time a single puse is 'on' can be calculated by: 1/(frequency*2) There will be 60 pulses per second. O The time between two consecutive pulses is 60 ms The tmebenutive pulses 8 16.7 ms The time between two consecutive pulses is 167 ms The time between the start of consucutive pulses can be calculated by: 1/frequency The time between the start of consecutive pulses can be calculated by: 1/(frequency*2)

Answer 1

Question 1 :

There will be 60 pulses per second. The time between two consecutive pulses is 16.7 ms since T = 1/f = 1/60 = 16.7 ms The time between the start of consecutive pulses can be calculated by: 1/frequency Since time period = 1/frequency
