Construct a combinational circuit that has a 4-bit 8421 BCD digit as its input and generates the corresponding 4-bit gray code BCD digital output. The circuit also has a single bit output V. If the 4-bit input is not a valid 8421 BCD digit, V = 0; else V = 1. If V = 0, (the input is not valid) the gray code BCD outputs are don't cares.
Find the generalized fourier series coefficients corresponding to these basis signals for the signal x(t) = 0.5(t-1)^2 in the interval 0
A current element of length 1cm is located at (1m, 3m, 4m) in free space and carries a current of 20mA along ay. An infinitely long filamentary current of 12A along az passes through the coordinate origin (0,0).
If we wish to design a communication system which carries voice securely, we need to ensure that others cannot tap into the conversation. In digital transmissions, we can do this by encryption.
A distortionless transmission line operating at 125 MHz has characteristic impedance = 40-ohm, attenuation constant = 0.02 Np/m and phase constant = 0.75 rad/m. Find the resistance and inductance per unit length for the line.
use any extragates in existing ICs for inverters when possible. Connect thecircuit and check its operation. the truth table for F1 and F2obtained from the circuit should conform with the minterms listed.
What is the minimum number of bits required to represent each of the following decimal numbers: 10, 1000, 100,000, and 1,000,000?
Consider a steady flow mixing process. Under what conditions will the energy transported into the control volume by the incoming streams be equal to the energy transported out of it by the outgoing stream
Use rail voltages of +/-15V. Sketch the circuit diagram and the voltage transfer characteristic (Vout vs Vin) Discuss how you chose the values of the components and comment on how accurately you think you can achieve the specification.
8 bit DAC with a 5 volt reference connects to a light source with an intensity given by Il=45V^(3/2)W/m^2 a. what is the range of intensity that can be produced b. what intensities are produced by digital inputs of 1bh, 7ah,9fh,e5h
The delay is an integral multiple of slot time. The numberof slot times to delay before the nth retransmission attempt ischosen as a uniformly distributed random integer r in the range0
A)what is the maximum Doppler for a vehicle speed of 160 km/hr at 900MHz. B)what is the minimum doppler(most negative for this case) C)for this range of Doppler what is the corresponding speed at 1800MHZ
A certain oil filled 100 MVA three phase transformer is rated at 345 kV / 25 kV, 75 degree C temperature rise, FOA, 60 Hz, connected delta / grounded wye. The equivalent circuit of the transformer has leakage impedance of Z
