1. Explain how an inverting amplifier is used in a high-impedance probe (X10 and X1).
2. In Fig. 18-1, why does the probe see a high impedance? Explain how the voltage gain is calculated in each switch position.
find the MIN permissible SAG for a span of 225 m using a copper conductor with 1.2 cm diameter and allowing a MAX conductor tension of 2200 kg/cm^2 . The horizontal wind pressure is 6 g/cm^2 and specific gravity of copper is 8.9
- Describe in your own words, what "the tarp" or "the landscape" represents - what do the hills and valleys convey
Find phase current,line current and power taken from the mains. - What would be the above values if one of the resistors were disconnected?
Consider a separately-excited dc motor. Describe the speed variation of the motor operating unloaded under the following conditions:
Why is it that the hypothetical but illustrative energy cost is smaller in this problem than the one in Example 2.8?
how a transformer works and apply those rules to a transformer where the primary core cross-sectional area is twice.the
Suppose that two optical guides embedded in a substrate such as LiNbO3 are coupled as in the below figure and the transmission length Lo=10mm. If the coupling separation d is =10µm, n = 2.2, the operating wavelength is 1.3µm
A 20-cm length of wire moves at 15m/s in a constant flux density of 0.4T. The wire, direction of motion, and direction of the flux are mutually perpendicular. Determine the voltage induced in the wire segment.
find all minimum sum of products expressions. ( if there is more than one solution ,the number of solutions is given in parentheses.) label the solutions f1,f2.... a) f(w,x,y,z)= Σm(1,3,6,8,11,14)+Σd(2,4,5,13,15)
Two amplifiers are cascaded, one with a voltage gain of 6.02 db and the other with a voltage gain of 12. If 10 mV is measured at the input of the second amplifier, what is the voltage at the input of the first amplifier
In the second section you are required to build an Arduino based voltage tracker. The ultimate task of the system is to output analogue voltage that tracks the set point voltage. Set point sampling rate is toms. Draw a detailed flow chart represen..
Design a synchronous circuit that implements a 4-bit decade (modulo-10) counter (0000,0001, ..., 1001, 0000,...) a. Fill in a transition table (using don't cares for undefined next states).
