We need to use the signal from a piezoelectric vibration sensor in a computer-aided instrumentation system. The signal is known to contain components with frequencies up to 30 kHz. What is the minimum sampling rate that should be specified? Suppose that we want the resolution of the sampled values to be 0.1 percent (or better) of the full range of the ADC. What is the fewest number of bits\ that should be specified for the ADC?
Given the following difference equation with the input-output relationship of a certain initially relaxed system (all initialconditions are zero), y(n) - 0.7 y(n-1) + 0.1y(n-2) = x(n) + x(n-1)
What is the phase response for {h[n]}? That is, what is the phase versus ω of H(e^jω)?
How much steam is required for each pound mass of entering acid, and what is the concentration of the hot acid?
Calculate the speed of sound
Which is the best alternative to buying a machine assuming an interest rate of 4% and a time span of 6 years. Compare using Present Values. A: Buy new machines for $25k. They earn $5k per year and their maintenance costs are $125 per year.
find values of resistance, voltage, and current for total and all 3 voltage drops where only certain information is given out of three voltage drops info given total voltage is 12v, resistance 1 is 2.2KO, resistance 2 is 1.6KO, and resistance 3 is..
A balanced three-phase inductive load is supplied in steady state by a balanced three-phase voltage source with a phase voltage of 120 V rms. The load draws a total of 10 kW at a power factor of 0.85. Calculate the rms value of the phase currents
Construct a block diagram and an ASMD chart for digital system that counts the number of people in a room. The one door through whichpeople enter the room has photocell that changes a signal x from 1to 0 when the light is interrupted.
The binary-coded-decimal (BCD) format uses 4 bits to represent 10 decimal digits. For example, 259 in base 10 is repesented as "010 0101 101" in BCD format. A BCD incrementor adds 1 to a number in BCD format.
Synchronous Satellite Link: Consider a 2 GHz link between asynchronous satellite and a ground station on the equator. The bandwidth of the up-link and down-link are the same. The orbital radius of the satellite is 36,000 Km and the radius of the E..
A source emits seven messages with probabilities 1/2, 1/4, 1/16, 1/32, 1/64, 1/128, and 1/128 respectively. Find entropy of the source. Encode this source using tartary Huffman coding, that is, encoding it using three symbols, say ‘0', ‘1', and ‘2'
Two point charges q1 = 2.0 C and q2 = 1.0 are fixed in a plane at the positions given by the Cartesian coordinates shown in the figure at right. Consider that they are in a vacuum, where ko = 9.0 × 109 N.m2/C2.
