The chip was powered by applying 9V DC between pin 14 and pin 7 also the waveform of Va, Vb and Vc was recorded also the oscilloscope frequency was measured.To interface oscillator with the amplifier, the following was done;• The oscillator was linked with the amplifier by connecting the dashed line on figure 2.0To estimate the power delivered to the to the load, the following was done• The loud speaker was replaced with the load resistor R(load)=10R• The waveform of the voltage drop across the R(load)  and Vload was recorded• The top level of Vload, V(top) was measuredTo check how the power affects the amplitude of the load, the following was done• The supply power was reduced from 9V gradually and the corresponding reduction Vtop value was notedTo study the effect of component value on the oscillation the following was done;• For the values of  R=1k, 10k, 620k and 3.3M, the Vc was monitored and the frequency measuredTo improve the tune, the following was done.to 4.11V.On disconnecting the value of R1, the value of peak-to-peak voltage changes to 24mV.From this, it can be observed that this is a very large decrease and therefore R1 plays a very important role in the circuitChanging the value of R1 reduces the voltage and also the peak-to-peak value. Increasing it increases the value peak-to-peak value. Input voltage increase to 4.11V. ...Download file to see next pagesRead More
