A 74x163 counter is hooked up with inputs ENP, ENT, and D always HIGH, inputs A, B, and C always LOW, input LD_L = (QA.QC)', and input CLR_L = (QB.QD)'. The CLK input is hooked up to a free-running clock signal. Draw a logic diagram for this circuit. Assuming that the counter starts in state 0000, write the output sequence on QD QC QB QA for the next 15 clock ticks.
If each gold atom donates one electron to the gold matrix at room temperature, estimate the electron concentration of gold. Is gold a conductor?
Describe the steps in the keypad polling routine. Draw a flow chart for the keypad LCD software code. Discuss challenges experienced in developing the keypad LCD software code.
What is the effective data rate of this transfer (not counting the time for reading or writing the DVDs)?
Binary symmetric channel, Assume that we are transmitting binary digits over a binary symmetric channel. Let p(x=0)=p(x=1)=0.5.
An LED is rated at VF=1.6V to 2.0V at IF=20mA. What value of series resistance is needed to limit the LED current to 20mA when this LED is connected to a 32 v peak source (that is, a source having a peak voltage of 32 v)
Implementation of the project with the analog and digital modulation techniques
A rectangular loop of wire in free space joints point A(1,01,) to point B(3,0,1) to point C(3,0,4) to point D(1,0,4) to point A. The wire carries a current of 6mA, flowing the az direction from B to C. A filamentary curent of 15A flows
Identify the types of system-building methods used by Dorfman to build its wireless warehouse system.
Box 1 contains 1000 Integrated Circuits of which 10% are counterfeit. Box 2 contains 2000 Integrated Circuits of which 5% are counterfeit. Externally, all IC's look identical. Two integrated circuits are picked from a (single) randomly selected bo..
A baseband signal has frequency components from 5 kHz to 15 kHz. Determine (a) the theoretical minimum sampling rate and (b) the maximum time interval between successive samples.
A. Determine the fundamental frequency w0, the period t0, and the coefficients in the representation X(t) = x0 + Re{(sigma)k=1N Xkejkwot} for the above input. C. Now consider a new signal y(t) = x(t) + 10 cos (50 pi t - pi/6). How is the spectrum ..
What would be the minimum sample rate needed to adequately acquire an EKG signal Note that this problem is not as simple as it appears to be, because while the fundamental frequency may be relatively low, artifacts in the EKG may be at frequencies..
