D *4.82 Consider the circuit in Fig. P4.74 with two equal filter capacitors placed across the load resistors R. Assume that the diodes available exhibit a 0.7-V drop when conducting. Design the circuit to provide ±12-V dc output voltages with a peak-to-peak ripple no greater than 1 V. Each supply should be capable of providing 100-mA dc current to its load resistor R. Completely specify the capacitors, diodes, and the transformer.
