1. Does the common emitter amplifier produce a considerable amplification effect and if so, are the results consistent across transistors?
2. Does the common emitter amplifier produce a phase shift at the output and if so, is it affected by the transistor beta?
3. If the collector and base voltages had been measured with the oscilloscope DC coupled, how would the measurements of Table 21.5.3 have changed?
4. Does the value of the transistor beta play any role in setting the input impedance? Was a considerable variation in input impedance apparent?
