design a 40% duty cycle square wavegenerator circuit with an adjustable frequency of between 1 to 10KHz. The output should have an adjustable linear output voltagerange of between 0 to 5 V and be capable of supplying a current of150 mA throughout the voltage range. The design should include acircuit schematic and provide complete specification of allcomponents used in the design. The design description should show all calculations that have been made to size the components andprovide all justifications why you have chosen the design and component specifications.
