“**Knows his stuff!**”

Hello there Student,

My name is Mark O., and I grew up in Revere, MA. I went to Revere High School then got my BSEE degree in Electrical Engineering from Northeastern University. While working, I took 33 graduate course credits in Electrical

Mark is approved to conduct lessons through Wyzant Online. Wyzant Online allows students and tutors to work remotely via video, audio, and collaborative whiteboard tools. For more information about how online tutoring works, check out Wyzant Online.

If you’re interested in online lessons, message Mark to get started.

We went over the basics of Signals and Systems and how to plot different functions in MATLAB and in Octave.

so satisfy. very prepared. he helped me in my advance course in Linear system. I learned a lot and understood the material.

Mark is a huge help and I am so thankful! My son is improving and has a much better understanding of precalculus! Before Mark started tutoring my son he was failing precalc.... he got a 94 in his last test!!

Approved subjects are in **bold**.

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

I built my first IBM based PC back in the early 80s. I worked for Wang Laboratories at the time and used the Wang PC extensively as well (both DOS operating systems). I tailored autoexec.bat and config.sys system files for optimum performance. I still use the "command" DOS prompt to do things that Windows will not let me do.

I have a BSEE with Honors from Northeastern University, 33 graduate credits from UMASS Amherst/Lowell with a 4.0 GPA and an online certificate from MIT in EE. I have worked over 33 successful years designing Control and Communications products. I hold a patent in cable TV technology: "Cable television control apparatus and method with channel access controller at node of network including channel filtering system."

I have used Linear Algebra extensively during my career as an Electronic Engineer. I mainly used MATLAB and MathCad for simulating a telephony channel used to transmit DSL signals. In order to provide an accurate end to end channel model the DSL modem hardware had to be modeled as well so I used matrix methods to model the electronic circuitry in the modems. I used 2-port chain matrices to model the general circuitry over all while the solution to systems of equations using determinants and inverses where used to model the more complicated 3-port hybrids. I used the rank of the resulting matrices to validate the integrity of the model. I used vector calculations to simulate the over all frequency domain simulation. I used systems of over and under determined equations to perform a least squares best fit data model for some of the circuit components characterized by empirical laboratory data. I used optimization techniques of matrix theory methods including Differential Evolution as well standard optimization techniques to characterize some of these empirically defined components such as multi-winding transformers. I used vector characterizations of mean and standard deviation of the frequency domain vectors to obtain the the DC and AC RMS power contained in these vector signals. I mentored colleagues in the application of the techniques I had developed and form the basis for two patent applications.

I worked over seven years developing data communication system channel models using MATLAB extensively. I developed numerous data communications simulation utilities in MATLAB. I wrote several dozen data comm. modem hardware circuit simulations using the symbolic processor in MATLAB. My channel modeling work was the basis for Time Domain Reflectometry patents applications.
