## Homework Statement

When testing the circuit of FIGURE 1 (a) it was found that the output shown in FIGURE 1 (b) was obtained when the input was connected to ground.

explain why this was so and attempt an estimate of the capacitance values of C.

## Homework Equations

## The Attempt at a Solution

estimating the waveform as 7ms the formula f = 1/T was used to get the frequency of 142.857Hz

assuming C1 = C2 and R1 = R2

the formula f = 1/2πCR was used, rearranged into C= 1/2πfR to give capacitance as 111uF.

any help is much appreciated in giving me any advice as to whather this is correct.
