Well, that was a long time ago, but as best I can recall I knew how to:
- bias many different kinds of transistors to form amplifiers, oscillators, switches
- use resistors, capacitors and inductors to create circuits that did useful things with AC current
- understand the resistance, impedance, current flow, voltages and power flow in a circuit
- use vector algebra to analyze complex variables
- apply thevenin and norton theorems and kirchoff's laws to circuit analysis, how to reduce circuits to simpler equivalents
- how meters work
- the affect of series and parallel impedances on a circuit, resonance, coupled ac circuits
- the nature of the relationship between an arbitrary time domain waveform and its frequency domain equivalent
- basic calculus
- programming an 8080 in assembler
- programming in BASIC and Fortran
- how to use a huge variety of simple logic ICs.
- how to use many kinds of linear ICs like op amps, regulators
- design of digital counters, state machines, many other small circuits
- the internal architecture of a microprocessor
- how to make RF measurements
- how transmitters are modulated to send radio signals, the nature of common types of modulation, the nature of noise
- the architecture of a radio receiver, and how to demodulate AM, FM, SSB
- how to use transmission lines, especially coaxial ones
- how radio waves travel in space, how antennas work (basically, not enough to design them)
- how to repair and tune a radio
- how to make a circuit board
- how to understand the value of a resistor from the color bands on it
- how to solder. how factories solder.
- how to write a technical report
- how to understand data sheets for ICs and other parts
- how to draft an engineering drawing for a part or a schematic
- the basic physics of semiconductor devices
Anyway, the list goes on.
As for the kind of work I could get, well, i was called a Technologist which is one up from a Technician. Around here a technologist can find a job in maintenance, in building new systems, in factories. My first job out of college was as a maintenance tech for the local police department, working on installing and maintaining all the telecom and radio stuff around a major city. There were five techs in our little team, and sometimes I would be on call to deal with emergencies like when a repeater failed or something. I got some interesting helicopter rides along the way.
Later on, working in a manufacturing company, i hired many people including technologists for R&D jobs, mostly in a lab. It is fair to say that in that situation there was a kind of class structure where the engineer with the engineering degree had better opportunities and wider variety of work than the technologist. The tech was usually doing assignments for an engineer, whether that was building up circuit board assemblies for testing, or doing testing, for example.
It is important to realize that there is a wide range of quality in graduates from any program. Where you fall in this range of quality is usually a reflection of how much work you put into it. The ones that are passionately "into it" to the point where electronics is their hobby as well as their work were the ones who got the best jobs. Its because they learned the most in school. Why? Because they really paid attention, and they did their homework, and ultimately they understood most of what they are taught, and then they practiced what they learned on the weekend by building something and figuring out why it didn't work. The ones who merely passed the exams adequately often did not really absorb 50% of all they were presented with, and so are not capable of doing some of the most interesting work. For example, designing circuits is full of detail and if you didn't pay attention to absolutely everything in school you would struggle with designing circuits. The guys who were only fair in school would be doing well to join a larger company with an in-house training program and stick that out for a few years, and perhaps aspire to being a plant supervisor as an example, after ten years or so. If you are patient, this can pay off, but things go a lot faster later on if you work harder in school to begin with. I have known many engineers that got to senior positions within five years of getting out of university, mainly because they were very sharp guys. I've also known many technologists that got to the same position, but it took them twice as long as the engineer with the degree.
