LECTURE: TV Systems & Signals

Today, has been an eventful day mainly due to the snow that has been falling constantly for the last 24 hours. This morning there was only a light dusting of snow on the ground, so I risked it and went to uni as usual, no problems getting in. It was whilst I was at uni, things started to go bad. The snow just kept falling and falling, which i knew was bad right from the start, even though it wasn’t settling at North Greenwich.

This morning we had a practical tv systems and signals lecture with John Palmer. We looked into termination of video signals, and why it was important. which was an interesting lecture. and it surprised alot of us, how much the signal changed based on if it was terminate or unterminated.

At the end of this lecture, the snow was still falling and I was now dreading trying to get home.

Another Electronics Practical in the afternoon, and the snow was still falling, by this time, my dad had phoned me to say we now had nearly a foot at Petts Wood, and that it will be hard trying to get home.

I finally left uni at 5pm, and got to Lewisham via the Jubilee Line and DLR with no Problems. Lewisham had still only 2-3 inches of snow and trains were running ok, into London. MY train arrived about 10-minuets late and was said to be fast to Orpington, which was fine for me, just meant a slightly longer walk back.

We Pulled out of Lewisham and moved slowly down to Hither Green, where we stopped and the opened the doors. This wouldn’t have happened if we had been the true fast service that they had said in Lewisham. We had stopped because there were 5 other trains in front of us trying to reach the South East, all being blocked by one train that had broken down at Petts Wood.

After 3 hours of very slow moving and long waits at stations we finally made it to Petts Wood, the snow is in deed over a foot deep, and there are only two lines out of the usual 4 the could just about be used. Walking back from Petts wood station was just as dangerous, with next to no grip on the compacted snow.

I don’t think, I’ll be going to uni anytime soon.

This is my first real blog post for IPP / Fluxity and its on Electronics and TV Systems and Signals. This is still right at the start of the course for us, so we are starting right at the beginning with the Electronics and Tv Systems and Signals.

Electronics

Starting with the basics over the last few lectures, we looked into the fundamentals of Electronics, this included:

  • The Atom
  • Charge
  • Voltage
  • Current

Most of this I had covered previously in at A Level, but these lectures stood as a handy recap. Over these lectures we also covered Resistance, Power, and Capacitance, all at a fundamental level, to provide the building blocks for later lectures.

Tv Systems & Signals

Tv Systems and Signals is a completely new unit for most of us on the course. with these first couple of lectures covering the very basics, starting with the Broadcast Chain and The EM Spectrum. Both topics although basic provided me with a huge insight into the broadcast world and how its not as simple as just watching TV makes it seem. This small insight into the industry has spurred me on to find out as much as I can about being a Broadcast Engineer
