R1=1.5D3;//resistance R1 in ohms
R2=1.5D3;//resistance R2 in ohms

R4=12D3;//resistance R4 in ohms
C1=0.068D-6;//capacitance C1 in farads

//Solution

T1=0.693*R3*C1;//time period of initial part of waveform in seconds
T2=0.693*R4*C2;//time period of final part of waveform in seconds
T=T1+T2;//total time period of waveform in seconds
f=1/T;//frequency of wave in hertz
