Question

QUESTION 6 In an inverting summing amplifier circuit, two inputs are given (check here to show): V1 peak - 2.0 V (square) and V2peak = 1.0 V (triangle) at 500 Hz Draw one cycle of V1, V2 and Vout on the V-t graph paper (here) when R1 - R2. After complete your drawings, write your name on the graph, take a photo or save it to a jpg file and submit below Attach File Browse My Computer Browse Content Collection Browse Dropbox

Answer 1

Given opamp based inverting Summing amplifier 1 . The two inputs vifv₂ are ] V, Ipeak) = 220V ( Square) V2 (peak) = loov (Triangle) Both with frequency, f= 500Hz So, timepewrode Tata So.- 2 msec The output of this inverting Summing amplifier is given as I Vos -(V, TV2) formula is given a l in the question itself ! Also, here Rp = R2 (as per question) so, Vo = -(Vi+vz)] • Here, we only need to plot voltage time (uz) graph

-TV

By adding above two waveforms point-to-point, we get (V1 + V2) (V1 + V2) UNT -3V

Now just multiply with (-1) in the above (V1 + V2) waveform to get Vo waveform. Vo- (V1 + V2) -3LN
