Why is it not necessary to write a function prototype and function header line/body when using a function from a standard library?

A. You have to use the prototype and function header line.
B. The prototype isn’t defined until the code is compiled/
C. The library substitutes compiled code for the linker.
D. The library defines the function, so the program can just use it.

D. The library defines the function, so the program can just use it.

This problem is about designing LSI graph filters using least squares. An LSI graph filter can be defined through its frequency response h ( ? `) at its distinct frequencies ? `, for ` = 0 , 1, . . . , N ? 1. In the weight matrix based DSP G framework, an LSI graph filter is a polynomial (in the weight matrix) of degree M. To construct an LSI filter with frequency response h ( ? `) = b `, one need to solve a system of N linear equations with M + 1 unknowns h 0, h 1, . . . , h M

In general, N > M + 1, and therefore, the system of linear equations is overdetermined
and does not have a solution. In this case, an approximate solution can be found in the
least-squares sense.
Design the filters with the following specifications using least squares for the graph shown in
Figure 10.7.
(a) A low-pass filter of order two that passes only the smallest two frequencies.
(b) A high-pass filter of order two that passes only the largest two frequencies.
(c) A band-pass filter of order two that passes only two frequency components ?2 and ?3.

Speedy Spuds is a fast-food restaurant offering all kinds of potatoes. The manager has a 30-second rule for serving customers. Servers at the counter say they could achieve that rule if the form they must fill out and give to the kitchen crew were simplified. The information from the completed form is keyed into the computer system at the end of the day, when the data entry person needs to enter the kind of potato purchased, additional toppings purchased, the quantity, and the price charged. The current form is difficult for servers to scan and fill out quickly.

a. Design and draw a form (you choose the size, but be sensible) that lists possible potatoes and toppings in a manner that is easy for counter servers and kitchen crew to scan, and can also be used as input for the inventory/reorder system that is on the extranet connecting Speedy Spuds and Idaho potato growers. (Hint: remember to observe all the guidelines for good form design.) b. Design and draw a representation of a display screen that can be used by the servers and clerks to fill in the information captured on the form. c. Design a display screen based on the display you designed in Problem 5b. This time, it should function as a display that shows a kitchen crew member what to prepare for each Spuds order. List three changes to the existing display that you made to adapt it to function as an output display.
