Challenge 1

Challenge 1 -comment

The challenges may introduce new concepts as well as concepts that were supposedly covered in other courses.  If an unfamiliar idea is encountered feel free to ask for help from your instructor or your classmates.  Often a problem discovered in lab will highlight important elements so that the focus during the lecture will turn toward the problem encountered in the lab.

Week1

Simulating SiPM photo detectors

challenge 1  was to simulate the action of a SiPMin response to light based the article above.  In pursuing this goal the basic operation of the SiPM and the way the model incorporates these features needs to be considered.  I have some thoughts: random thoughts on SiPM op. & modeling.  Wait on this part until challenge 2 is complete.  (Lots to do this will become an extra credit problem.)

Challenge 2  Simulate, Calculate, Build

·    RC charging circuit

·    RLC circuit

·    parallel and series LC circuit.

Comments on Impedance

Do you understand components?

 challenge 3  DRC  voltage dividers and AC –DC conversion

 challenge 4 part 1 improve your AC circuits  DRC

 

    Week6  DRG Transistors

challenge 4 cont. DRG build a voltage amplifier  Refer to the web reference below.

Build an emitter follower and describe how you decided on the Q-point and clarify what function an emitter follower performs.

Build a current amplifier and explain how you established its quiescent values. Build the amplifier on the protoboard and show it working.

  Week 8 transistors

Challenge 5:  Use a long cable and an oscilloscope to explore the properties of pulse transmission in a cable. Terminate the cable with various resistors and describe what happens.  Be sure to describe in detail what happens and the measurements you made of the process.  To test if you provided sufficient detail I may have your results read by a junior physics or math major.  They should be able to understand what you did.  Some oscilloscopes can record images that can be imported into a document.
