An AC circuit design for balancing a load in AC circuits. The only power supply availablehas an internal resistance of 75Ω. The load has a resistanceof 600Ω. You want to deliver the maximum power possible tothe load by properly selecting X1 and X2. This can be done bymaking the source's output impedance look like 75 +0jΩ. Select X1 and X2 to accomplish this.Once this is done, select the capacitors and inductors needed forX1 and X2 to have previously calculated values at ω=106rad/s. What is the Thévenin impedance seen by the 600Ω load resistor?
A serial transmission is set up for 8 bits with odd parity. The first two bytes of data are 01110111 with parity bit 1 and 01101010 with parity bit 0. From this we know that there are no errors in transmission.
Determine the half power frequency fc defined as the frequencyat which the magnitude of the transfer function is at 1/√2 ofits maximum value. Assuming C is fixed at 0.02 μF, calculatethe half power frequencies corresponding to R=20 kΩ, 50kΩ, and 1..
