A differential pressure bellows sensor is receiving 20 kPa (gauge) on one side and 90 kPa (absolute) on the other. What pressure does the sensor report?
A description of the operation with simple calculations based on an appropriate transistor model (include the emitter resistance concept).
a) Plot the spectrums for the range from 0 Hz to 25000 Hz. Make sure to label the frequncies. b) sketch the recoverd analog signal spectrum if an ideal lowpass filter with a cutoff frequncey of 4.5 kHzis used to filter the sampled signal.
False positive and false negative rates can be adjusted, and they are often complementary: Lowering one raises the other. List two situations in which false negatives are significantly more serious than false positives.
give the definition of electrical circuit. draw the simplest electrical circuit and mark the directions of electrical values in it and ohms law. what are the main and the additional elements of the electrical circuit and that are the purpose.
Discover the basic concept of electronic rectifiers and build up the basic skill of electronic fault-finding and electronic design. You understand the applications of rectifiers design.
An overhead line with an inductance of 1.33 mH/km and capacitance of 8.34 nF/km is connected to an underground cable with an inductance of 0.266 mH/km and capacitance of 166 nF/km.
In region 1, defined by z>0, there is a magnetic field of H= 4.8x ˆ 6y ˆ +8z (A/m) and the relative permeability is 50. Determine the magnetic flux density B in region 2, z
A circuit that is made from a voltage source in series with the switch then in series with the parallel set of a resistor and a capacitor. The switch is originally open, it is then closed.
A battery E (e.m.f 12v and internal resistance 0.8 ohms) and a resistor R1 (10 ohms) are connected in series across two parallel resistors (R2 = 12 ohms, R3 = 18 ohms). i) Draw the circuit diagram, determine the battery terminal voltage.
Vo(t) = RC (dVi(t)/dt). Suppose you have a triangle waveform as input to the differentiator with 100pF capacitance and 100 Ohms. The peak to peak voltage of the triangle waveform is 10Vpp and its frequency is 100k Hz.
if you use the sinusoidal waveform to drive the speaker: What change in the sound do you expect to hear when you increase the amplitude of the sinusoidal signal on the function generator
Suppose a certain causal signal f(t) has a Laplace transform F(s) = 1. If f(t) is sampled at times kT where T is a constant time interval and integer k>=0, what are the sample values
