Introduction
Using a JFET transistor based microphone, the aim of the project is to amplify a low
current speech signal from the microphone to be digitised and recorded on to a computer
processor.
Referring to the lab document[1], transistor amplifier c
Carbon Trading and Developing Countries
The idea of carbon trading is that members of the Kyoto Protocol are to set an
emission credit, which allows each member to emit certain amount of carbon
dioxide. When a country is unable to control their emission,
Direct FM
For direct FM, the instantaneous frequency is directly varied with the information
signal. The carrier frequency is varied using an oscillator where its resonant frequency is
determined by variable components. The oscillator frequency modulates
Generation of FM
The FM systems have some definite advantages.

Firstly, the excessive power dissipation due to extreme peaks in the waveform
need not be bothered.
Secondly, the non liner amplitude distortion has no effect on message

ChElh: HEAT TRANSFER
As long as there is a temperature driving force
between two points heat will be transferred down
the temperature gradient (from hot to cold).
Why study heat transfer?
We need to be able to understand how we can control
temperature.

Heat exchangers & their sizing
For a heat duty, Q, (in W), what heat transfer area
is required?
Heat transfer without phase change: sensible
heat is added to or removed from the stream.
Q = GcpT
Heat capacity: cp is in J kg1 K1 or J kmol1 K1
