Seven-segment displays are commonly used in calculators to display each decimal digit. Each segment of a digit is controlled separately, and when all seven of the segments are on, the number 8 is displayed. The upper right segment of the display comes on when displaying the numbers 0, 1, 2, 3, 4, 7, 8, and 9. (The numerical designation for each of the digits 0 to 9 is shown in Figure P5-40 and described in more detail in Section 12-6.) Design a circuit that outputs a HIGH (1) whenever a 4-bit BCD code translates to a number that uses the upper right segment. Use variable A to represent the 23 BCD input. Implement your design with an AOI and inverters.
A 3000-V, 1-A dc power supply is to be designed with less than a 4 percent ripple voltage. Compare the pros and cons of implementing this power supply with half-wave, full-wave, and full-wave bridge rectifiers.
Determine the normalized impedance at λ/8 from the load if (a) its normalized impedance is 2 +j, (b) its normalized admittance is 0.2 - j0.5, (c) the reflection coefficient at load is0.3 + j0.4.
