1. Analogue communication system
2. Digital communication system
Analogue communication system is the electronic communication system such as telephone, equipment designed to carry only voice transmission, which is composed of continuous electrical wave. Examples of analogue systems are telephone box, television set with knob, clock or watch etc.
Digital communication system is the electronic communication system designed to process data as digital signals which are individual electrical pulses that represent the bits that are grouped together in bytes. It is a series of the numbers one i.e. 1s and zeros i.e. 0s. Examples of digital systems are digital watch, mobile phone, digital camera, remote controlled TV etc.

CONTENT:
The components of GSM transmission are:

(b) Mast
(c) MTSO (mobile telephone switching office)
(d) Telephone (mobile phone)
WORKING PRINCIPLE
A GSM telephone uses radio waves to communicate with a local antenna assigned to a specific geographical area called mast. Each mast range from one to ten miles in width and uses between 50 and 75 radio channels. When a call is made from a GSM telephone, the signal is picked up by the nearest GSM antenna. The antennas are located in masts from one to ten miles wide. The GSM antenna relays the signal to the mobile telephone switching office (MTSO) which directs the call to the receiver, when the call is being made to a conventional telephone, the signal enters the regular telephone system lines through which it will get to the telephone.
EVALUATION:
Mention the components of GSM transmission.
Explain the working principle of a GSM.
ASSIGNMENT:
Write briefly on the working principle of the internet.

Ceramics are used for making articles such as:
1. W.C (modern toilet)
2. Portrait
3. Ceramic bakery oven
4. Electric socket
5. T.V screen
6. Electric stove
7. Concrete or block
8. Spark plug.
Glass is a type of ceramic that is composed of sand (silica), soda and lime. These major ingredients are mixed and melted to such a temperature that all the gases are given off and a clear liquid is obtained.
FORMS OF GLASS
1. Sheet glass
2. Plate glass
3. Rolled glass
EVALUATION:
State the properties of ceramic.
Mention the use of ceramic.
Mention ceramic materials.
ASSIGNMENT:
Mention 5 uses of glass.

WEEK 6
TOPIC: USES OF MATERIALS (PLASTIC AND RUBBER)
OBJECTIVE: At the end of the lesson, the students should be able to:
1. Mention two types of plastic.
2. Mention uses of plastic.
CONTENT:
PLASTICS
Plastics exhibit both physical and chemical properties which vary according to the different types.
TYPES OF PLASTIC
1. Thermoset or thermosetting
2. Thermoplast
USES OF PLASTICS
Plastics have properties such as low tensile strength and low specific gravity. As a result of some of these properties, they have found wide application in many different fields.
The uses of plastics include
1. Aircrafts and automobile parts: they are used as:
(a) Fuel filters
(b) Insulators
(c) Accelerator and clutch pedal covers etc.
2. Industrial use
(a) Plastic bottles
(b) Containers
(c) Storage bottles etc.
3. Household items such as:
(a) Buckets
(b) Cups
(c) Spoons
(d) Water pipes etc.
EVALUATION:
Mention the types of plastics
State the use of plastics

LESSON 13
TOPIC: GEOMETRICAL CONSTRUCTION (LINES)
OBJECTIVE: At the end of the lesson, the students should be able to:
1. Mention types of lines.
2. Draw and state the uses of lines.
CONTENT:
LINES
There are different types of lines in Technical Drawing and these lines serve different purposes.
Line is the extension of point when two lines meet at a point they form an angle.
A Straight line is the shortest distance between two points.
TYPES AND USES OF LINES
LINES------------------------------------------------------------USES
Thick Continuous Line ________________________For visible outlines and edges
Thin Continuous Line ________________________For dimension lines, projection lines and construction lines.
Thick Long Chain Lines ____.____. ______ .___ For cutting and viewing planes
Thin Long Chain Line _____.______.____._____ For centre lines
Short Dashes __ __ __ __ __ __ __ __ __ __ For hidden outlines
Thick Continuous Wavy----------------------------------For short break and boundary lines
Thin Continuous Wavy---------------------------------------For limits of partial views
Thin Ruled Line with Short Zig-Zag------------------------For long break lines
Arrow Head Lines ↔ ---------------------------------Used at the end of dimension lines and for direction.
EVALUATION:
Mention types of lines and state their uses.
Draw the following lines arrowhead, zig-zag, short dashes, thick continuous line, etc.
