• Designing a Full Wave Rectifier..?

    Now I have to design a full wave rectifier, it's kind of like a bridge rectifier only with a capacitor in parallel with the load resistance. What I need to do is find the values of R and C (resistance and capacitance respectively) so that the small signal voltage across them is less than 200mV. The only data i have is: the primary Voltage... show more

What I need to do is find the values of R and C (resistance and capacitance respectively) so that the small signal voltage across them is less than 200mV. The only data i have is: the primary Voltage (Vp) is a 6 Vp sinusoidal voltage source operating on 60 Hz. The input signal enters a transformer having N1=155 turns and N2=310 turns. and assuming the diode is a CVD model with Vd=0.7 I have NO IDEA where to start from. I need help, please? here's a snapshot of the problem: http://i299.photobucket.com/albums/mm309... Thank you!

  • Calculus Help? Domain & Range of an exponential function..?

    Find the Domain & Range for the function g(t) = √[4+7^(-t)] *Square root of 4 + 7 to the power of -t* I know that what's under the root shouldn't be negative, & I try using logs, but you can't use the log of something negative so I'm stuck. Help? pleaaase? :D
