The sinusoidal voltage source in the circuit is developing an rms voltage of 2000 V. The R2= 6 homs load in the circuit is absorbing four times as much average power as the R1 = 20 ohmsohms load. The two loads are matched to the sinusoidal source that has an internal impedance of 500 (angle) 0
1)What is the numerical value of a1?
2)What is the numerical value of a2?
3) Calculat the power delivered to the 20 ohm resistor?
4) calculate the rms value of the voltage across the 6 ohm resistor?
What is the path attenuation between transmitter and receiver at a frequency of 1.2 GHz and a distance of 11,000. Given: f = 1.2GHz d = 11,000 mi. Calculate the path attenuation; dB = 37dB + 20 log f + 20 log d = 37 + 20 log 1.2^9 + 20 log 11,000
On Earth, we assume normal room temperature is 293 degrees Kelvin. From this, we find that the power spectral density of thermal noise is -174 dBm/Hz. On Venus, the average surface temperature is 462 degrees Celcius.
a) Using K-Map, find the minimum product-of-sums for the following function. Circle the term on the map and write the result in algebraic form. b) Draw the block diagram in NOR-NOR.
If the concentration of free electrons is 10^29 electrons per cubic meter and if they are uniformly dispersed throught the wire, then what is the average velocity of an electron ?
The ALU required for this lab accepts two 4-bit inputs (A0 - A3, B0 - B3), a 3-bit function selection code (F0 - F2) and outputs a 5-bit result (S0 - S4). Since the function selection uses 3-bits, there are 8 different functions.
Use the simulation timing diagram to compare the worse case time to do an operation with your ALU with the worst case using the 74LS381. State which operation takes the longest and list the time required for both ALU's.
A majority function is generated in a combinational circuit when the output is equal to 1 if the input variables have more 1's than 0's. The output is 0 otherwise. Design a 3-input (A, B, C) majority function. Use K-maps to simplify the circuit. D..
