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?
1. Obtain the compete state diagram showing both used and unused states and transitions. It is a self-correcting design 2. If the design is not self-correcting - modify it to obtain aself-correcting design. Show the work and draw the circuit diagra..
4. Your measurement device samples data every 0.1 minute. What is the heart rate you will measure 5. How will your measurement change if the sampler period goes down to 0.01 minute 6. How will your measurement change if the sampler period goes up to ..
The average for the Harry Potter weekends is 36.5, with a standard deviation of 0.7. The corresponding numbers for the other (control) weekends are 67.4 and 10.4. Use a t test to investigate the claim that the small number of injuries during Harry..
Each of the protons in a particle beam has a kinetic energy of 3.30 10-15 J. What is the magnitude of the electric field that will stop these protons in a distance of 1.05 m
Design a counter that counts according to the sequence 0,5,1,4,2,3 in the ways listed. Provide a state diagram and show how unused states connect to the counting sequence. a. using T-Flip Flops b. using D-Flip Flops
The electrostatic potential in space is given by the scalar field V(r)=V(x,y,z)=e^y + (3x)^2-4cos(z) Find the potential difference between the points P(1,1,1) and Q(0,0,0).
The charge that enters the BOX is shown in Fig. 1.20. Calculate and sketch the current flowing

An audio signal s(t) generated by a loudspeaker is reflectedat two different walls with reflection coefficientsr1 and r2. The signal x(t)recorded by a microphone close to the loudspeaker, after sampling,is: x(n) = s(n) + r1s(n-k1) +r2s(n-k2)
Consider a separately-excited dc motor. Describe the speed variation of the motor operating unloaded under the following conditions:
An AC motor with impedance Z = 4.2 + j3.6 O is supplied by a 220 V, 60 Hz source. Determine the time average power delivered to the load.
Design a linear unregulated power supply that will provide an average of 500mA to a load at 15 volts average. Use a 12.6 VRMS sinusoidal source.
