( 2marks) Find the value of frequency at which the magnitude equal (0.5 Hmax) b) The following circuit represents a filter 1- find he transfer function H(jw)= Vo(jw)/Vs(jw). 2- find the kind of the filter, center frequency, cutoff frequencies and quality factor R2 (5 marks) L + Vin(t) Question # 2 + - R1 L Vo(t) (5 marks) The following periodic signal Vi (t) applies to system shown, where V1(t) function of one period is given by V1(t) = 2 sin(2t) in the interval(0 , 0.5π) and zero in the interval (0.5π , π) Knowing that h1(t) = sign(t) and h2(t) = δ (t – 2) Find: Vo (t)
