Unformatted text preview: Their Fourier series are: t n n n V n m ,... 5 , 3 , 1 cos 2 sin 4 : wave Square ϖ π ∑ = t n n V n m ,... 5 , 3 , 1 2 2 cos 8 : wave Triangle ∑ = 3 where ϖ =2 π/ T with T being the period of the signal and V m is the maximum voltage. For which of these two waveforms is the ratio of the absolute value of the voltage of the fundamental with respect to the third harmonic the largest? For this choice, what is that ratio of the first ( ) to third harmonic ( V 1 / V 3  = __________)? Design a low pass filter that is another 7 db down at the third harmonic, compared to the first harmonic, and sketch the circuit below, under the assumption that T = 1 ms. Draw the Bode plot for your filter. By h ow much will your filter attenuate the fundamental? 4 Freq. (rad/s) 20 log ( V / V in ) 3 rd harmonic 0.1 ϖ 1 ϖ 10 ϖ 100 ϖ2010...
