Crossover Distortion is the most common form of distortion in Class B type Amplifiers and occurs at the point of cross over of push pull NPN, PNP transistor arrangements. The simple push pull Class B arrangement below illustrates the point well.
When the input is zero neither of the base emitter bias for both transistors are biased for conditions for conduction to occur (this is when for NPN transistors, for PNP transistors then no significant conduction occurs). The output in such cases remains essentially at zero. As the input bias rises slightly above zero, but still remains below +0.65V, the NPN transistor stays "off" and the output remains very nearly at zero (apart from some very small conduction below the knee of the NPN input/output characteristic which results in a ...
A brief outline of the main cause and effects for distortion in Class B Type amplifiers and the main ways to reduce such affects
Australian Financial Regulation
Read the attached article about the 2008 financial crisis and calls for better regulation in "Leaders: What next?"
The article refers to corporate and regulatory failure. It poses the proposition that better regulation is needed but it must be the right regulation. Further, it suggests that too much regulation may inhibit the market and make it less effective.
Consider whether there is a need for any reform of the law relating to the supervision of financial services in Australia and whether too much reliance on regulation is naive?
By following this guideline you will be successful in this task:
Use relevant legal principles, case law and legislation and their application to provide an answer to the problem. Present arguments in a clear, concise and logical manner and that conclusions shall be reached.
Have excellent, concise understanding of the key regulatory issues and laws
Have excellent research that is thoughtfully and logically integrated within the essay. Extensive use of a range of resources.
Demonstrate an excellent understanding and analysis of key policy issues and provided comprehensive and sophisticated critical insights
Have an excellent conclusion which clearly and succinctly explained the chosen outcome
Have an argument that is consistently clear and the essay is well-structured
I have only assigned this task to you and also attached a 'Helpful links' document as well as 3 other documents to assist you.
