Determine if the following waveforms are orthogonal over their respective restricted joint intervals, show all work sketch g1 (t) and w (t) in each case. case 1: g1(t)= α1cos(ω1t+ φ1) 0< =t< =1/2f1g2(t)= β2sin(ω2t+ φ2) 0< =t< =1/2f1 α1=constant , φ1= -πβ=constant, φ2= 2πf1=f2= ω1/2πcase 2: g1(t) as in case 1, -1/2f1 < =t< =0g2(t) as in case 1, -1/2f2 < =t< =1/f2all other parameters same as case 1
