hey guys. Need some help on my project-based learning problem.
It about displaying television picture(flickering). And i will quote the part where i need help and hopefully i can get some help from you guys. Here
To prevent flickering,the time needed to perform this "painting" must be completed within 1/60s
"One method of generating such a waveform is to repeatedly charged a capacitor with a large time constant , and repeatedly discharges it with a very small time constant . The sawtooth generation circuit and its waveform is shown in Fig.2."
Q2. With reference to the sawtooth waveform in fig2,calculate the value of R1 in order to produce the charging voltage shown.
how to find resistor,R1? i need help here. Thanks a lot.
