(Choose two answers.) a,c 4. A PC NIC and a switch port create one electrical circuit to use when sending data from the PC to the switch. The transmitter uses a simple encoding scheme that uses a higher amplitude to encode 1 and a lower amplitude to encode 0, sending 1 bit in each bit time. The bit rate is 2000 bits per second (2000 bps).
Figure 2 shows a circuit with a resistor R = 1.0 × 103 Ω, and a battery with potential difference of VB = 5.0V . (a) Solve the circuit in Figure 2. That is, find all unknown currents, voltages, and resistances. (b) What is the direction of the current? Note: I want the direction of the conventional current.

Class d is used for multicasting, hardly ever used. RFC 1918 It describes a set of network ranges set aside for private use. They are used for home, office, and enterprise local area networks. It was made to conserve ipv4 before it was
Be sure to put your answer in Sum-Of-Products (SOP) form. 6. Design an AOI logic circuit that implements the simplified logic expression Decision. Limit your implementation to only 2-input AND gates (74LS08), 2-input OR gates (74LS32), and inverters
Connecting the Circuit 4. Changing the Name of the Part 5. Changing the Value of the Part 6. Making Sure You Have a GND 7. Voltage and Current Bubbles 8.
Under the assumption that current and voltage are both sinusoidal functions of time (t, in seconds) and both have the same frequency of 60 cycles per second (period=1/60), let C be the current in Amperes (Amps) with a maximum current of 5 Amps at zero seconds (t=zero). Let V be the voltage that is “leading” the current (‘leading’ corresponding to a negative phase shift) by .003 seconds, meaning voltage reaches its maximum of 180 volts .003 sec before the current reaches its maximum. Both functions begin at zero- there are no phase shifts. Question 1, Part A. Current as a function of time: Based upon the given information, we will be determining the Amplitude (A), period (and thus, B), and the phase shift (C).
To be able to show all 16 possible numbers 0-15 you can change the circuit so that the most significant bit (the eights place) is shown by an LED and the rest of the number is displayed on the MAN72, this would then be a successful binary to octal number system conversion circuit. Lab 4 – Logic Gates Materials: - 7400 quad 2-input NAND gate - 7402 quad 2-input NOR gate - Two 1.0 kΩ resistor Purpose: The purpose of this exercise was to set up a simple NAND or not and gate and a NOR, or not or, gate. Once set up, using one of the resistors to ground for a logic of one and a simple jump to ground for a logic of zero, the goal was to test the truth tables for these two gates. Procedure: The setup was incredibly simple, we simply set up and VCC’d the ICs and then began to test. The trouble came when our results were not matching the anticipated theoretical results.
