Lab #0: Sept 13 & 14

Instructions [link] and [formulae]

• Complete lab
• In person or assistance via zoom
• Write up lab
• Submit by 27 Sept [Extended deadline]

Issues:

• Picoscope kit is missing cable
• Capacitor is 2.2uF
• Use 10Hz and 100Hz instead

SYSC3203: Fall 2021. © Andy Adler

Lab#0 Part 2: c) Calculate the 20 % and 80 % voltage levels, given a 2 V p-p input signal:

​

​

2Vpp

80% of 2V is 1.6V

​

20% of 2V is 0.4V

​

Use the Picoscope’s moveable vertical and horizontal markers to estimate the rise time (20-80%) and fall time (80-20%) of the output signal (Figure 3).

Calculate using formula (V(T) - V(0)) = (V(inf) - V(0) )exp( - t/tau)

Online Labs

Numerous students are missing online labs.

• It is your responsibility to get the work done
• ask for help if you need it

​

1. Kits were shipped to those outside Ottawa. Extra items will arrive this week. For these students, there is an extension to lab due dates
2. For online lab students in Ottawa, you need to pick up wires and components in the lab (during lab hours)
3. Help is available by zoom (regular course zoom)
1. During Mon and Tues labs (14:30 - 17:30)
2. On request at other times

Circuit Drawings

Many labs require circuit drawings.

See image at right for an example.�Doing a proper drawing will help layout and debugging of the work.

Online lab students

• Online Lab 5 will be marked by me. Students must prepare a *working* circuit and email me for a time during the lab hours. I will view the circuit and its output.
• For labs 0 - 4, the instructions require showing the output of the circuit. Writing “person X saw it” does not meet the requirements.

Crystal Oscillator

Note: Bad circuit. Do not copy

Crystal quartz has the capacity to absorb, store, release and regulate energy. It resonates with all of the chakras as well as each Zodiac sign. Quartz enhances spiritual growth, spirituality, awareness, and wisdom [/sarcasm]

Picoscope

What is Δ of a picoscope with 8 bit converter

​

When set to –20V to +20V?

​

Δ = Range / L = (40V)/2⁸ = 16mV

​

When set to –50mV to +50mV?

​

Δ = Range / L = (100mV)/2⁸ = 391µV

Lab Kit Returns

All students must return the course lab kits.

• Remove all components from the boards. Active components, chips and diodes should be put back into the foam they came from. Resistors, capacitors and connection wire for the circuit are considered consumables and can be thrown out.�
• Book a curbside drop-off time through the [link], and return your kit at the time. All students must have an appointment. No kits will be accepted outside of a scheduled appointment.�
• Kits will be inventoried to identify any missing components. Ensure the kits are returned as close to the way they were given out at the beginning of the term. Kits are expensive and any missing components are the responsibility of the student.�
• When before Dec 17 or after Jan 5

Biomedical and Electrical Engineering Program Feedback

We are consider a program change for the Carleton University BMEE program and are soliciting feedback from BMEE students.

• ELEC 3908 Physical Electronics was a compulsory course in BMEE (and still is in Electrical Engineering (EE))
• BMEE program evolved to allow students a choice between ELEC 3908 and SYSC 2004 Object-Oriented Software Development (SYSC 2004 is a compulsory course in other programs such as EE, Computer Systems Engineering (CSE), and Software Engineering (SE))
• Recently, BMEE program evolved again to allow students a choice between ELEC 3908, SYSC 2004, and SYSC 2010 Programming Project

We are considering removing this choice and making SYSC 2010 compulsory for BMEE.

SYSC 2010 – Programming Project

Calendar Course Description

Programming, testing, and debugging of small�team-based software projects that use data �from sensors to display results graphically. �Modern programming tools: frameworks, libraries, version control, package management, tool chains. Sensors, signal acquisition, display, and basic filtering. Introductory network programming.

Course Structure / Model: Core of the course is project work

Labs - Focus on project-based application of skills�First 8 weeks – students (in pairs) will build a complete functional program. Uses a sensor device (shown) to create an actual neuropsych test�Last 4 weeks – students innovate from this core based on your interests.

Lectures – provide knowledge to support the project work

Other Key attributes:

Biomed applications applied and discussed through-out the course.

Uses many typical tools that are common in industry for development� Build your resume using tools/methods like Agile/Sprints/GIT etc

Instructor: Dr. Bruce Wallace, wally@sce.carleton.ca

• question 1 of the practice quiz for a 555 timer. It is required that the circuit function as an astable oscillator with output low- and high-periods of 20 ms and 30 ms, respectively. To make this happen, draw appropriate connections and select resistors RA and RB. This is what I thought but I'm not sure about this. Could you clarify what to do with the separate resistors?
• Quiz 30 minutes, 8:20 - 8:55

• Q1,2 from 2019Q4
• Can you please solve Quiz 7D: Fall 2016 (last question)
