A generator provides the following voltage signal: v(t) = 2 + 3 sin(100pi) + 4 cos(250pi). Find the average value of the function. Note: pi = 3.1416 in this equation?
Shannon's Law describes the relationship between bandwidth, signal power, and noise in determining the theoretical maximum Capacity in bits per second of a particular communications channel.
Three amplifiers with power gains of 15, 22, and 7 are cascaded. The input power is 120 µW. What is the output power of the final amplifier stage
Consider the function F = x · y + x(not) · z. a) Expand the function to its canonical or standard sum of products (SOP) form. b) Express the function in its canonical or standard product of sums (POS) form.
How does noise affect the measurement signals in analog and digital data lines. Why is one signal sensitive to noise and the other one is not
The average noise power per unit bandwidth measured at the front end of an AM receiver is 10^(-3) watt per Hertz. The modulating wave is sinusoidal, with a carrier power of 80 kilowatts, and a sideband power of 10 kilowatts per sideband.
Semiconductor A is direct band gap and semiconductor B is indirect gap. For providing same short circuit current density of a solar cell, which material will need more thickness
Assume that an oven has an electronic thermometer attached to circuitry with two outputs: one (H) is asserted when the temperature is above h, and the other (L) is asserted when the temperature is below l. Design a circuit that will turn the oven
a certain shunt motor armature has a resistance of 0.07 and a current of 50 amperes at 120 volts. determine the counter emf
A given signal f(t) is multiplied by this periodic signal. Determine an expression describing the spectrum and the time waveform of the resulting amplitude-modulated signal if all componets except those centered at + Wc
Digital Communications uses a few specific modulation formats. Research at least 5 different applications or standards and explain what modulation format is used and what is the bandwidth over which you need to equalize the channel? Determine the ..
What is the main operation when a comparator cascade with an active third order low pass filter, with a feedback of output to input.
An array is defined as: ARRAY DB 2 DUP(5,2,2 DUP(4,7),6) The location of ARRAY is at 500H and DS = 0 Select an instruction to read the third copy of 4. Select one: a. MOV AL,ARRAY[SI] :where SI=10 b. MOV BL,[500] c. None of the answers. d. MOV [BX+SI..
