- Built an amplifier and placed it in between the 40kHz square wave output of the 555 timer circuit and the emitter. Hooked up the signal at the output of the amplifier to an oscilloscope as well as the signal at the receiver. Our experimental setup as well as the results are shown below:
- Our results were problematic. For one, the output of the amplifier was heavily distorted (it should've been a clean square wave), though the amplitude was still around 13Vpp (which it should've been). Furthermore, the received signal was much weaker than expected. We were only getting 72mVpp, when we expected much more.
