Figure 9.45 shows a programmed PAL device using fuse-based interconnects. Examine the logic diagram and determine the logic block implemented by the PLD. A cross (×) represents an unprogrammed interconnection and a dot (•) represents a hard-wired interconnection.
The analog signal cos (200t) is digitized using a sampling frequency of 300 Hz, and a quantization of 8 bits per sample. How many bits will be used to store 2 minutes of the digital signal
HALF-ADDER: S = XY' + X'Y , C = XY (These are the outputs) 1. From the equation given for half-adder, develop an equation for which the half-adder can be constructed just with NAND gates. Draw the circuit as per the equation obtained.
An 11000V/230 V. 50 Hz, single phase, core type transformer has a core section 25cm X 25cm. Allowing for a space factor of 0.9, find the suitable number of primary and secondary turns, if the flux density is not to exceed 1.2 T.
Determine the first four values of the modulation index β for which the carrier component is reduced to zero and determine the approximate bandwidth of the FM signal
What exposure (in Roentgen) does full scale deflection correspond to? What absorbed dose in air, and tissue, does it correspond to?
a step-down transformer has primary turns np 100 secondary turns ns 10 primary winding resistancerp 100 ?secondary
If you had to build a voltmeter with a d'Arsonval movement, what current sensitivity would you need if the meter were to have the same internal resistance on the same voltage scale?
show that the most probable electron energy in the conduction band of a semiconductor is kt2 above the bottom of the
find the number of years that the country can go without constructing a generating plant before the load exceeds the generating capacity. Assum a 5% annual growth rate in demand.
a) Determine the frequency range of the local oscillator for this receiver b) Analyze and explain whether it's possible for this reciever to receive both a diesred AM station and an image station within the same 31-meter band
a. Create 10000 random variables uniformly distributed between 2 and 4. b. Create a histogram to approximate the actual probability density function. c. Superimpose the actual probability density function to the above histogram.
Two circular poles of the electromagnet, facing each other, both have a radius of R=0.1 m. The electromagnet is suddenly disconnected from its power source, and magnetic field decreases at a rate of 2.0 x 104 T/s.
