Fourier transform Test Questions
and Answers

frequency: - Answer--number of times that a periodic event repeats itself for some
standard interval of time

-Hz

-correlates to pitch perception

- F= 1/T

Period: - Answer--duration of a cycle
-(s) or (ms)

phase: - Answer-timing of wave propagation: in phase of out of phase

propagation velocity: - Answer-speed of sound (about 35,000 cm/sec)

wavelength: - Answer--distance between recurring events

velocity-frequency-wavelength relationship: - Answer--c=(frequency)(wavelength)
-frequency= 1/T

c=velocity (cm/sec)
wavelength= cm
frequency=Hz

difference between sine and complex waves: - Answer-sine has 1 frequency, complex
has additional frequencies

fourier analysis: - Answer-any periodic waveform, no matter how complex it is, can be
closely approximated by adding together a number of sinusoidal waves

what is the relationship between fundamental frequency and harmonics? - Answer--sine
waves that add together to make a periodic complex wave are harmonically related

-those sine waves are called harmonics

-the harmonic with the lowest frequency (the 1st harmonic), is the F0 of a complex wave
