What are the fundamental frequencies for a 50 kHz square waveform of 50% duty cycle and a 25 kHz sinusoidal waveform, respectively? (The duty cycle of a square waveform is the ratio between the pulse duration and the pulse period.)
My teacher then gave an example to illustrate v(t) and cn. Hence, I have a feeling that I should use these formula to find the answer.
The Attempt at a Solution
I am at a loss of which equation to use because there are too many representations of v(t) and cn in my lecture notes. Nevertheless, I shall attempt o solve the above question.
For the square wave, with its frequency at 50kHz, which is f0, its period, 1/f0 is 2X10-5 seconds. I don't understand what does T stand for in the equation, but I assume it refres to the amount of time the signal was turned on. Since the signal is ON for half the time, T will be 1X10-5.
Hence, I will have
Am I correct?
May I have some hints as to how to start the question for the part on sine wave?
Thank you everyone. :)
