Reference no: EM13963181

The figure attached shows the Armstrong oscillator. A transformer with two secondary winding's has been use, one to give feedback and one to give the oscillator's output. Write a short report [two to three pages] on an investigation into the operation and performance of this circuit 1.

The report should embrace, as far as you are able, the following themes:

(a) Why should the output be taken via the transformer rather than directly off the collector of the transistor.

(b) Calculate quiescent voltages on the three terminals of the transistor.

(c) calculate the frequency of oscillation.

(d) The shape of the output waveform in the first 10 milliseconds of start-up.
