Problem : Find the voltage gain of the circuit shown on the right. Consider the gain for the special cases of
a) R5 → 0
b) R5 → ∞
explain how you would modify a 4-bit adder circuit to turn it into an Adder/Subtractor circuit. Explain how your creation would do a subtraction operation. Use a circuit diagram to illustrate. For an Adder/subtractor that works with signed numbers
Design a micro grid of PV rated at 100KW of power and at 230 V AC using a PV module with the following voltage and current characteristics. Determine the following: Number of modules in a string for each PV type Number of strings in an array for ea..
What is the minimum number of pins required for a socalled dual-op-amp IC package, one containing two op amps What is the number of pins required for a so-called quad-opamppackage, one containing four op amps
A pressure measurement system is stated as having the following characteristics. Range: 0 to 140 kPa; Accuracy: ±1.5% of the displayed reading; Temperature sensitivity: ±0.1% of the reading per °C If the instrument indicates a pressure of 120 kPa
The signal transmitted by a Base Station has a power of 1 mW at a distance of 1 m from the transmitter. Measurements have shown that the propagation exponent for the path loss is n=3 up to a distance of 1 km and n=4 beyond that.
two antennas at the same location on earth receive a signal from a satellite directly overhead at altitude h 36.0
by using the laplace transform compute the convolution xtvt of the two signals where xte-tut and vtsin
a) what is the frequency f, of the ac circuit signal b) what is the period, T, of the ac circuit signal what is the angular velocity/frequency (omega), of the ac signal if v(t) = 24 cos (2pie 500t).
a. Plot the spectra of X(w) = t sinc(wt/2). Let t = 1 and -20 =
a pn-junction is uniformly doped and has dopant concentration of na 4 x1016 cm-3 in the p-region at 300k. at zero bias
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
It is decided to apply a Fast Hopping (FH) scheme on the above ASK system. The hopping is made over 12 channels of 100 kHz; or over 1.2 MHz bandwidth. The ASK signal hops 6 bands per bit period. Now a strong jammer randomly jams one of the 12 FH c..
