Question 1
If we need to have a frequency resolution of 50 Hz or better and a time resolution of 10 microsecond or better, and we want the number of data points to be a power of 2, what is the minimum number of data points necessary for a Discrete Fourier Transform of a signal? What is the resulting sampling and Nyquist frequency? (9 pts)

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...

. It takes sound waves of frequency 500 Hz 14.7 ms to make a roud rod waes of freqec round trip through a hollow pipe of length 7.5 m filled with helium. What is the speed of sound in helium? Show your calculations.
The scale on the horizontal axis is given by 5ms/div. What is the frequency
(in Hz)? State your answer to 3 significant figures (no
units). (Note: You should be able to estimate the period
from the graph to within 0.1 div. Consider 2
periods.)
It is desired to produce a musical note having a frequency of 280 Hz. (air temp 20°C so speed of sound = 343 m/s) a.) what tension should be placed on a guitar string that has a mass per unit length of 6.80 grams/ meter? the string has a length of 18 inches between anchor points. b.) an organ pipe open at one end and closed at the other end is used to produce the same note. what should be...
