Loop cards are a great game that can be played individually or as a class. They are perfect for review key vocabulary or questions at the end of a topic or when revising for an exam.
Instructions
Cut out the cards from the paper horizontally (but don't cut them in half!) and then shuffle them.
Now start joining each question on the right hand side of the card to the matching answer on the next card.
Carry on until all the cards loop together and you have competed the game!
Hint: Make sure that you set your paper to portrait to print 4 cards per sheet of A4 paper.
The process of converting the continuous amplitude values of an analog signal to discrete values (binary digits) in a digital signal.
JPEG
A lossy compression algorithm used primarily for digital images that achieves high compression ratios with minimal loss of image quality.
Entropy Coding
A compression technique that takes advantage of the statistical patterns in the data to encode it more efficiently, by assigning shorter codes to more frequent patterns.
Nyquist Theorem
States that the highest frequency that can be represented by a digital signal is half of the sampling frequency.
Binary form
Representing sound using only two possible values, 0 and 1, using a series of bits.
Convert
To change a number from one numbering system to another.
Signed integers
Numbers that can be positive, negative or zero, represented by a sequence of bits in a computer's memory with a sign bit.
Resolution
The number of pixels in an image, usually measured as width x height.
Bit
The smallest unit of digital information in a computer, representing either a 0 or a 1.
Character Encoding
Character encoding refers to the method used to represent character data in a computer. It assigns a unique code, known as a code point, to each character.
