Design a digital time clock that displays hours, minutes, seconds,and tenths of seconds. The clock should use the 12 hour format anda PM/AM indicator. Use BCD coding for each digit of the clock. Finally, assume that common cathode LED displays and 5V TTL gatesare used in your clock. Your design should use the minimum amount of hardware and a periodic 60hz clock signal.
What is the value of RTH?
Unpolarized light is incident on three polarizers: The first making an angle of 0 degrees with the vertical; the second making an angle of ? degrees with the vertical; and the last one making an angle of 90 degrees with the vertical.
Determine the range of DC current that can be applied to coil 2 without saturating the core when coil 1 has a steady 10A DC current in the direction that makes the flux flow CW on the ring . The Current at coil 2 has the same direction as the curr..
Derive the transfer function for a system with an function u(t) and an output function x(t) described by the following differential equation; d^3x/d^5d^2x/dt^2+17d^x/dt+13=d^2u/dt+6
The frequencies of the tones are 100 Hz, 300 Hz, and 450 Hz. The sampling rate is 1 kHz. Describe a low pass, a band pass, and a high pass filter that could be used to detect the individual tones.
find a minimal two-level NAND realization for each of the following switching functions. a) f(A,B,C) = sum m(0,2,3,7) b) f(A,B,C,D) = sum m(0,2,8,10,14,15) c) f(A,B,C,D,E) = sum m(4,5,6,7,25,27,29,31)
A lossless transmission line with the electrical length of l = 0.3 lamda and the characteristics impedance of Z0 = 75 is terminated with a complex load ZL = 30 -j20 calculate the reflection coeficient at the load, the SWR on the line
Compute the maximum and minimum spectral frequencies received by a mobile traveling at a speed of 100 Km/hr. What is the frequency of the received signal if the mobile is moving in a direction perpendicular to the direction of arrival of the trans..
Consider a symmetrical square wave of 20-V peak to peak, 0 average, and 2-ms period applied to a Miller integrator. Find the value of the time constant CR such that the triangular waveform at the output has a 20-V peak to peak amplitude.
Consider a square house 40 ft on a side, 10 ft high, with a flat roof on top and walls/roof that is 8 inches thick. The thermal conductivity for an un-insulated wall or roof is 1.6 W/Km, while with fiberglass insulation its 0.04 W/Km.
Brown and Vranesic. Problem 6.28 - Repeat Problem 6.26 using T flip-flops. Design a three-bit counterlike circuit controlled by the input w. If w = 1. then the counter adds 2 to its contents, wrapping around if the count reaches 8 or 9.
(a) What is the magnitude of the average acceleration of a skier who, starting from rest, reaches a speed of 9.38 m/s when going down a slope for 3.89 s (b) How far does the skier travel in this time
