3 weeks is all the time that is left until the first year of my college course comes to an end and it is only until today when I had my first practical session. A whole years worth of theory and enough math’s to burn a hole through the brain has led up to this one laboratory exercise, which turned out to be rather disappointing in a way that it was easy peasy. It was simply to design and construct a wane bridge oscillator circuit using a 741-operation amplifier.
