1.)Consider the noise level table included in page 2 and thedesign equations included in pages 3 and 4 for circular and square membranes. Consider the radiusof the circular membranes limited to values ≤500 μm and square membranes with sides ≤1000 μm. Plot the corresponding thickness versus radius for (i.) rustlingleaves, (ii.) conversational speech(iii.) loudly reproduced orchestral music in a large room and(iv.) a home lawn mower.
(2.) Employ the thickness values obtained in (1.) to generate plots of maximum stress versus thickness/Radius ratio. Explicitly indicate if the membrane sreach (or exceed) the rupture stress value of silicon.
A load is delivering 1400 VARs of reactive power at a power factor of 0.96 leading. Determine the complex power S and the average power P for the load.
Assume that the initial energy stored in the inductors shown in the circuit is zero. Find the equivalent inductance with respect to terminals a and b
What is the transformer used for in a full wave rectifier Can you make a bridge rectifier without a transformer What are the advantages of using a transformer If you initially have a transformer with a 1:1 ratio
Fortunately, for this purpose, we can replace multiplication with switching operation. A similar observation applies to demodulators. In the scheme depicted in fig p7-40a, the period of the rectangular periodic pulse x(t) shown in Fig. P7-40b is T..
The receiver takes the three received bits and decides which bit was sent by taking the majority vote of the three bits. Find the probability that the receiver makes a decoding error.
Design a UV flip-flop using a JK flip-flop and two logic gates. where the characteristic table for the UV flip flop is U V Q(t+1) 0 0 1 0 1 !Q(t) 1 0 Q(t) 1 1 Q(t)
A sinusoidal current is zero at t = -0.625 s and increasing at a rate of 8000pi A/s. The maximum amplitude of the current is 5 A. a. What is the frequency of i in radians per second b. What is the expression for i
The pressure of the gas within the bag remains at 1 atm and its temperature remains at room temperature 20.0 Celsius. How many moles 'n' have been introduced into the bag by the time its volume reaches 22.4 L
An Alternator is found to have its terminal voltage on load condition more than that on no load. What is the nature of the load connected
A 20kg of aluminum block initially at 80C is dropped into an insulated tank that contains 120 liter of water at 25C. Determine the final equilibrium temperature and the total entropy change for this process.
A combinational logic circuit has 3 outputs as described below: F1=Minterm(0,3,4) F2= minterm(1,2,7) F3= Maxterm=(0,1,2,4) Implement the circuit using a single decorder with active high outputs and external 2 input OR gates
A radio channel has a bandwidth of 10 KHz and a SNR of 15 dB. What is the maximum data rate that can be transmitted: (a) Using any system (b) Using a code with 64 possible states
