Build and test the circuits in the Day 2 Lab Addendum
Complete the rest of Lab 1 (1L.5 through 1L.6)

 

Day 3 – RC Circuits in the Time Domain (reverse lesson)

Chapter 2: RC Circuits – Read section 2N.1 & 2N.2; read 2N.4.2 and 2S.1

Here is a recorded video version of the discussion of capacitors in the time domain (56:59) It is optional but feel free to watch if you want a review or preview.
(Note this was recorded for the digital only class where we use capacitors much less often — so ignore those comments.) 

Lab Day 3

Analyze, then build and test the circuit in Lab Instructions Day 3, then complete the first half of Lab 2 in the book through part 2L.1.3.

Watch this explanation and demonstration of the use of bypass capacitors to reduce noise on power buses: Bypassing Demonstration Video (11:10)
(Again this was recorded for the digital only class so ignore the “not going to do anything with” comment.)

 

Day 4 – RC Circuits in the Frequency Domain

Chapter 2: RC Circuits – Read section 2N.3 to end of chapter; read 3N.1 and 3N.2; read 2S.2 & 2S.3

If you have not yet watched all the Oscilloscope Basics series of videos, please do so.

Lab Day 4

Lab 2: Complete part 2L.2
The Siglent oscilloscope has a built-in function generator and can automatically measure the Bode plot of a filter.  If you have time, feel free to create a Bode plot of the high-pass filter in part 2L.2.2 of the lab.  Here are the instruction from the scope user manual: SDS2000X-Plus_UserManual_EN01D_Bode_Polt.pdf

If you are unfamiliar with Fourier’s Theorem watch the demonstration video Fourier was no Fraud (8:03)

Lab Day 6

Lab 3: Complete Lab 3parts 3L.1  and 3L.5. (If your scope can create Bode Plots, try using it to display the output of the RLC filter in 3L.1.)

We only have a single antenna for part 3L.5 so we will have some of you start with this part to use the resource efficiently. Everyone should build the AM radio (3L.5) first on a separate breadboard. We will then call each group when the antenna is free. Continue to work on the rest of the lab once you have built the radio until your group is called.

Here is a short explanation of how the leaky peak detector in the AM radio works and some hints on testing and choosing component values: An Explanation of the Leaky Peak Detector

If we don’t have time for this demonstration in class, please watch MOSFET Switching Demonstration (3:44).

Lab Day 20

Lab 12:  Complete 12.1 through 12L.3. This lab has a lot of parts and it is unlikely you will have time to get to all of them. Here is the order we would like you to do the lab to get the most benefit from it.

Please try to get through the following experiments. (Note: signals denoted as “TTL” in the lab mean they have only two values: 0V and +4.5V. Configure your function generator to generate these signals.)

  • 12L.1 MOSFETs as digital switches. This is the most common use of discrete MOSFET parts and you should get comfortable using them, particularly to switch high current loads.
  • 12L.2.1 Analog switch imperfections
  • 12L.2.2 This section contains a number of applications for the DG403 analog switch. The most important is the sample and hold. Please try to get through it first.
  • When you finish the S&H, feel free to try any of the following: chopper circuit, the flying capacitor voltage inverter and the switched-capacitor lowpass filter (homemade version and integrated circuit versions) if you have time. The switched-capacitor filter is probably the most surprising application. You can build both versions or just the one you find more interesting. If you build the switched-capacitor filter and your function generator has two output channels, you can use one channel to supply the input sinewave and the other for the switch clock. If you build the chopper circuit, you can use the two channels to provide two different waveforms to display and the breadboard function generator for the switch clock (or build a LMC555 oscillator to generate the clock signal).
  • 12L.3 Class D amplifier (switching audio amplifier). This just involves hooking up an IC and is only interesting for the output waveforms going to the speaker. Feel free to skip it.

 

Day 21 – JFETs

Chapter 12: MOSFET Switches – Read 12S1.1 to end of 12S Supplementary Notes

 Day 22 – Phase Locked Loops

Chapter 20: Analog <-> Digital; PLL – Read 20N.6

Lab Day 22

Lab 20: Complete 20L.2

  • 20L.2.1 Build and test the circuit in Figure 20L.21.
  • 20L.2.2 Do the second part of this experiment first, testing the Type I phase comparator. (Since you want to use the divide-by-1024 output of the counter for these tests — that should give an input frequency range of 39Hz to 244Hz.) Compare the Type I (XOR) phase detector to the Type II (Edge Detector). See if you can get the Type I to lock onto a multiple of the input frequency. Now modify the PLL to use the divide-by-64 output of the counter using the instructions in 18L.2.3 to give a lock range of about 600Hz to 4kHz. Go back and try the FM demodulator in Part 18L.2.2. You can create an FM modulated signal with the new Siglent function generators (instructions attached). See how fast you can modulate the carrier and still recover the modulation sine wave. Try a  triangle wave and square wave modulation (you can try some of the built in arbitrary waveforms if the signal generator allows it).
  • 20L.2.3 See over what range the PLL remains locked.
