If this were a real circuit, what would be the sources of experimental error? (Remember experimental error does not refer to mistakes made by you) I am having trouble with this particular question. The is a lab on Resistors in Series and Parallel.
i) Create the simplified circuit for the ‘A’ segment. ii) In the same work space, create the simplified circuits for the ‘B’ and ‘C’ segments . Note: You are putting all circuit in the same work space because you will need to join all the different parts together at the end. Take a picture or screenshot and include here. iii) Connect the 3 circuits in i) and ii) simultaneously to produce the number 7. You will need to set the inputs W,X,Y,Z to 0, 1, 1, 1 respectively. Take a picture or screenshot of the circuit (with the LED display) and include it here.

In your own words, describe the difference between a Combinational and a Sequential circuit, including where and how they are used. Choose one of the circuits from the text, or found through research. Identify if the circuit is combinational or sequential and describe how it works/how it's used. (Include the circuit type in your posting title.) Create a diagram of the circuit and paste into your posting. (This is more difficult with some circuits, but if you end up choosing one that's too complicated you can create an approximation.)

PROBLEM #1 A 7-segment display is a common display device having 7 light segments that can be lit in different patterns to represent numbers and some letters. Each segment is assigned to a particular label: a, b, c, d, e, f, or g (as shown in figure to the right). To display a particular number or letter, each of these segments is either "on" or "off". Assume a "1" turns 'on' the corresponding segment and a "0" turns 'off' the corresponding segment. Problem description: You, as part of a team, have been hired by ACME University to design a display that reminds the departmental staff of the fiscal year by displaying the semester name and the last two digits of year. This semester, the message should read "FL2024" using 7- segment displays. Since only certain letters and numbers are relevant, the design team has decided to use a 3-bit CODE for each of the distinct characters needed for the SPR24 message. The encoding shown in the figure below. (Specifically, "000" will be used to…

You were tasked with modifying an audio amplifier circuit. Amplifier circuits are responsible for increasing the current sent to the speakers, avoiding damaging the sound device. The original design is shown in the figure. You want to increase the current I1 by a factor of 10 (10 times). The conditions of the design area are: Both font values must be increased. None of the values can be equal to 0. What are the new values that you propose for the design of the amplifier? ** Argue your answer by analyzing the results obtained through calculations.
