Preface
Programming in Java doesn't have to be dull and boring. In fact, it's
possible to have a lot of fun while programming in Java. This module is onein a series that concentrates on having fun while programming in Java.
Viewing tip
I recommend that you open another copy of this module in a separate
browser window and use the following links to easily find and view the Figureswhile you are reading about them.
Multiply-add operations
This module deals with a topic commonly know as Digital Signal Processing,
(DSP for short) .
Computational requirements for DSP
The computational requirements for implementing DSP in a computer program are
usually straightforward. Almost all DSP operations consist of multiplyingcorresponding values contained in two numeric series and then calculating the
sum of the products. Sometimes, the final sum is divided by the total number ofvalues included in the sum to produce an average. This is often referred to as a
sum-of-products or
multiply-add operation .
(This is the digital equivalent of integrating the product of two
continuous functions between specified limits.)
Typical notation
Such an operation can be indicated by the symbolic notation shown in
Figure 1
(where the strange looking thing constructed of straight lines is the Greek
letter sigma) .

difference between firm and industry
what's the difference between a firm and an industry
Abdul
firm is the unit which transform inputs to output where as industry contain combination of firms with similar production 😅😅

Suppose the demand function that a firm faces shifted from
Qd 120 3P
to
Qd 90 3P
and the supply function has shifted from
QS
20 2P
to
QS
10 2P .
a) Find the effect of this change on price and quantity.
b) Which of the changes in demand and supply is higher?

identify a demand and a supply curve
there's a difference

Demand curve shows that how supply and others conditions affect on demand of a particular thing and what percent demand increase whith increase of supply of goods
