Two bit Analog -to -digital converter-MatLab (711)Let X(t)= 0.8 cos(2*pi*t)+ 0.15, 0<=t<=1, and zero otherwise, be the input to a 2-bit analog-to digital converter. The four level quantizer corresponding to the 2-bit ADC is define askDelta<= x(nTs) <(k+1) Delta --> x'(nTs) = kDelta k= -2,-1,0,1where x(nTs), found above, is the input and x'(nTs) is the output if the quantizer. Let the quantization step be Delta = 0.5. Plot the inpu-output characterization of the quantizer, and find the quantized output for each of the sample values of the sampled signal x(nTs).
Design and simulate a power supply that takes line voltage(120v) and produces a 15V output with less than .5% ripple voltage with the following specifications use either full wave or full bridge wave.
what size capacitor should be placed in series with the series combination of 800 ohms and 20mH to give an admittance whose magnitude is 1m/ohm at w=10k rads/s
A HCS12 embedded timer is in PWM mode. If the E-clock is 24 MHz, the output period is 35.33 microsec, and a scale factor of 4 is used, what is the value loaded into PWPER
1. Derive boundary conditions for electric fields (both for tangential and normal components) 2. Derive boundary conditions for magnetic fields (both for tangential and normal components) 3. Why boundary conditions are so important in electromagnetic..
design the details of the D/A using a Weighted Resistor( NOT R-2R) technique, as well as the logic details of the sequencer/decision maker/state machine which sequences the A/D through its conversion steps to convert an analog input into a 4-bit b..
Calculate (i) the parallel capacitance C1 that would be required to change the power factor of the total load on the supply to 0.80 lagging and (ii) find the value of the supply current at this power factor
(a) Compute the minimum voltage that the output voltage across R1 falls to when both capacitors C1 and C2 are present. (b) Using the same model for D1, compute the maximum voltage that the output voltage across R1 rises to.
An H-bridge allows a 4 A current pulse to the drive motor. What is the average current if the duty cycle is 75% and the pulse frequency is 2 kHz
The armture of 2 -pole , 200 volts , wave wound DC machine has 400 conductors and runs at 300 r.p.m . Calculate the useful flux per pole.
The gain of the antennas must be increased when the TDMA system described in part (d) is used because the bit rate is higher than with FDMA and the noise power in the receiver is therefore higher
antimony pentafluoride,SbF5, is very strong lewis acid and can be used in combination with HF to form a superacid solution. predict the molecular geometry of SbF5 and draw its lewis structure.
Design a multi-function unit with 4 functions chosen using select inputs s1s0. The unit has two 2-bit inputs (A = a1,a0 and B = b1,b0) and 4-bit output (z3,z2,z1,z0). The unit performs A+B (s1s0 = 00), AB (s1s0 = 01), A2+B (s1s0 = 10)
