Design a low-pass RC filter with a break frequency of 30MHz. limit the value of the resistor to less than 1MΩ, and the value of the capacitor in the range of µF to pF. Draw the ideal bode plot (Av (dB) vs f)
this is the question, I kind of didn't get the question.
I tried to use the formula f2=1/2piRC
how would I use the formula to figure out the numbers...like use 1Mohm for R and rang of µF to pF ofr capacitor...and for y-axis it shud be gain in dB...so shud I increase by 20 db each time...very confused...
plz if any2 can help it will be great..thanks
will the graph on 4th quadrant...going from 0 db to -20 db, -40 db, -60db
