Design a comparator circuit to set off an alarm when the temperature in a boiler reaches 160°C. You have available a temperature-to-voltage transducer which generates a voltage of 5 V at 160°C and an alarm which activates at -15 V and is off for larger voltages. Sketch the transfer characteristics.
Chopper circuit has the parameters of a source frequenCy of 150 Hz and an on time of 3 ms. vohage of 90 V, chopper When this chopper drives an inductive load of 1.5 0 and 15 mH, determine the average load current.
However, in solving the semisupervised extension of this method, the representer theorem is the right choice. Explain the rationale for this statement.
For the diode that conducts 2mA at a forward voltage drop of 0.3vand whose n=2. Find the equation of the straight line tangent at ID=2mA
GaAs is composed of equal numbers of atoms of gallium and arsenicin a lattice similar to that of silicon. Suppose a siliconatom replaces a gallium atom in the lattice. Do you expect the silicon atom to behave as a donor or acceptor impurity
Compare the readings of two ammeters of unequal resistance when placed in parallel with each other and the combination inserted in series in a circuit.
A 25KVA transformer supplies a load with the following schedule: 8hrs-full load with 0.8 lagging power factor. 4hrs-75% full load at unity power factor. 12hrs-No load. The transformer is energised 24hrs per day and has iron losses of350w.
Calculate the inductive reactance per meter of a single-phase, 50-Hz, two-wire transmission line. Assume each conductor's radius is 9cm and the distance between the two conductors is 5m.
you want to generate a sinusoidal signal which frequency f varies continuously and parabolically from 500 hz to 3500
a) Find the two values of vGS that give there spective limiting values of resistance b) Estimate the maximum permissible amplitude ofvDS for this resistor to operate as a linear device
Please help me solve following question, thanks!!! Determine if the following signals are periodic and, if so, what the fundamental period is. (a) x1[n] = cos(0.8n);(b) x2[n] = cos(0.8πn+0.2π);(c) x3[n] = 3cos(0.8πn) + 4sin(0.5πn).
A cable technician tested the signal-to-noise ratio on the curb as 20 dBm. This means, if the noise power is at 1 mW, then the signal power should be 20 dB higher then that. If the noise power is 20 mW
The energy band gap of germanium is 0.72 eV at 300 K. the fraction of the total number of electrons ( conduction and valence band ) in the conduction band at 300 K
