Design a 1024x16 RAM using the 256x8 RAM blocks and neccessary combinational circuit. Note that, 256x8 RAM block has 8 bit data (DATA), 8 bit address (ADRS), chip select (CS), read/write (R/W) inputs and a three-state output bus.
The Hamming distance between two bit strings of the same length is the number of positions in which the strings have different bit values. For example, the Hamming distance between 1110 and 0101 is 3.
A three-phase steam-turbine synchronous generator is connected to an infinite bus. The generator excitation current is IF=1000 A at the time of synchronization with the bus. The generator has a synchronous reactance of Xs =1.5 per unit.
Write an assembly code segment that calls the subroutine New Function if bits 5 and 6 of PORTD equal 1. Write the same code segment in part (a) using structured assembly constructs.
Compute y(nT) iteratively for n=0, 1, 2, when, y(-T)=2, and x(nT) = u(n) Hint: the initial conditions are given for negative n. Shift the equation to the right to express x() and y() to eliminate all advances and end up with x(n), y(n)
Using a slotted line, the voltage on a lossless transmission line was found to have a maximum magnitude of 1.5 V and a minimum magnitude of 0.6 V. Find the magnitude of the load's reflection coefficient 'Omega'.
Write an instruction sequence to set bits 3, 2, 1, and 0 of memory location at $1000 to 1 and leave the upper four bits of the same locations unchanged. use hcs12/9s12 to program.
Why Can Discrete-Time FIR Digital Filters be a Linear Phase, Why can discrete-time FIR digital filters be made exactly linear phase, whereas IIR digital filters cannot?
Generate a new random variable X with pdf fX. Specifically, we want to generate a Gaussian random variable and relationship between Rayleigh and Gaussian distributions.
The RS-232 serial port on a personal computer is transmitting 2400-bit/sec data using a polar NRZ line code that has a peak value of 12 V. Assume that binary 1's and 0's are equally likely to occur.
Two amplifiers(CS) connected in cascade. The input voltage to the first stage has a source voltage Vsig and Rsig= 100KOhm. Rv=10KOhm AND IS CONNECTED TO THE DRAIN OF THE SECOND STAGE. BOTH TRANSISTORS HAVE Id=.25mA and Vov=.25V
Determine log10 0.2 = log10 18/90, and compare to log10 18 - log10 90.
Measurements show that for a particular arrangement of the equipment and at a particular amplifier setting, the system will howl if 1% of the output power is fed back to the microphone. Estimate the power gain of the P.A. amplifier in decibels.
