Mini project on Circuit theory

[audio]

Dear all,

I need mini project title for my 2 nd semester Circuit theory class.

We have been taught about DC Circuit analysis( basic laws, mesh analysis and nodal analysis) and AC analysis using phasor and steady state analysis. Our text is Alexander and sadiku.

We have been assigned mini project which could reveal learnt concepts.

You all can share your ideas. Thank you all.

Take a book about opamps, and then think of some circuits to measure some non-ideal properties of opamps such as offset, bias and offset currents, GBWP, and build them on a breadboard.

It's purely r,l,c and sources.

Make some filters and put audio through them to see how it makes the audio sound. Learn about input and output impedance when you try to listen to your output and hear absolutely nothing. Throw some transistors / diodes / opamps/ potentiometers in to start making guitar pedal circuits if you really wanna get fancy with it.

Did your teacher give you any idea about what type of projects you can choose? If you are only allowed to demonstrate what you've learnt so far, you can prove Ohm's law with a battery, a multimeter, and different values of resistors. You can also add LEDs to this project.
Have you studied the Hall effect? If yes, you can choose a Hall effect sensor based project. Those can be done with or without microcontroller depending on what components you are allowed to use.

A cool thing to analyse and present would be a classic 50s/60s electric guitar, eg, a Fender Stratocaster. There you have all the ingredients:
Inductance: the pickups, plus their inherent resistance and parasitic capacitance.
Resistance: volume control and amplifier input impedance.
Capacitance: tone controls and how they work.

The Stratocaster is especially interesting, as it has the option of paralleling two pickups giving an opportunity for further analysis.

Thank you sir

Dear all,

Request you all to share what are the possible mini project that can be done by the way of my syllabus.

It will be useful for my academics.

Thank you all..

You can make tests to find out the parameters of a real transformer or a real DC motor.
From the simplest parameters to the most complex parameters.

One possibility is a device for measuring the internal impedance of cells and batteries.
