Exercise 1:
Illustration 41:
Sawtooth in time and frequency domain
Here you see the whole DASY
Lab
window displayed. By far the most important circuit
for analysis and representation of signals in the time and frequency domain is to be found
at the top of the picture.
(c)
Create this circuit and visualise - as above - a periodic sawtooth without a direct
voltage offset in the time and frequency domain.
(d)
Measure the amplitude spectrum by means of the cursor. According to what simple
rule do the amplitudes decrease?
