DSP LEC - P1

Some of the signals are natural, but most of the signals are manmade. Some signals are necessary, some are pleasant, while many are unwanted or unnecessary in a given situation.

• True

• False

In engineering context, _________________ are carriers of information, both useful and unwanted.

extracting or enhancing the useful information from a mix conflicting information is a simplest form of ___________ ________________.

__________________ is an operation designed for extracting, enhancing, storing and transmitting useful information. Hence ______________________ tends to be application dependent.

operates through the use of discrete signals to represent data in the form of numbers

a parameter ( electrical quantity or effect) that can be varied in such a way as to convey information

a series operations performed according to programmed instructions

is an important field of study that has come about due to advances in communication theory, digital (computer) technology, and consumer devices

it is changing or analyzing information which is measured as discrete sequences of numbers.

provides many techniques in making things better.
