Electronic Schematics Diagram-The Four Commonly Asked Questions

Written by Jestine Yong

I came across quite a number of questions about electronic circuit schematics diagram. Most ofrepparttar question asked are: a) Do we really need a schematic diagram in order to repair any electronic equipment? b) Will schematic diagram help us to repair faster? c) At where we can get a particular schematic diagram? d) How to read schematic diagram ? Well,repparttar 144914 answers is as below:

a)-Theoretically yes, practically not necessary, it all depends on how good you are in electronic repair knowledge. For a beginner it is a 'must' for you to understand about schematic diagram, as you gradually gained more knowledge you will automatically depends less on schematic diagram. You will definitely need a schematic diagram when you come across a new designed or technology. For example, when comes to crt monitor repair i seldom see schematic because i already understood most ofrepparttar 144915 circuitry and section in a crt monitor. The new technology such as lcd or tft monitor makes me have to temporarily relies on schematic diagram. As my knowledge of lcd monitor repair grows, i will gradually depends less onrepparttar 144916 schematics. May be my situation is different from yours because i'm concentrating only on one type of equipment. I've seen quite a lot of repairers in my country that repair many types of equipment such as tv, video, vcd, dvd, amplifier, hi-fi, fax, laser printer, microwave and so forth. Most probably they need schematic diagram to keep them up to date on each ofrepparttar 144917 equipment technology.

b) If you have a particular schematic diagram for that particular equipment, your troubleshooting time can be reduced to half! Unfortunenately many manufacturer do not release their equipment's schematic diagram. If you depends on too much of schematic you will be stuck on how to repair that particular equipment. Why with schematic diagram you can repair any equipment faster? Because a schematic diagram shown you allrepparttar 144918 part list, waveform, voltages, explanation how that particular equipment work, block diagram, schematic design, component's part number, electrical schematics symbols, substitution, modification (if have) and electronic schematic symbols and etc. Assuming you have a power supply section blown and you could not recognizerepparttar 144919 component part number, but with schematic you will be able to findrepparttar 144920 exact part number and finally repairedrepparttar 144921 equipment.

Digital SLR Camera versus a Compact Digital Camera.

Written by Virginia Wong

Digital Single Lens Reflex (SLR) cameras are excellent cameras that produce clearer, sharper and more colourful images than most point and shoot digital cameras available. With prices falling rapidly, they are now more affordable then ever. Withrepparttar price gap between an entry model digital SLR camera andrepparttar 144724 most expensive compact digital camera narrowing;repparttar 144725 question is… do I spendrepparttar 144726 extra money and get a Digital SLR camera? or save a few hundred dollars and purchaserepparttar 144727 best digital compact camera. Well, it really depends on your budget; however if you do spendrepparttar 144728 extra money, here's what you get: In addition torepparttar 144729 price falls inrepparttar 144730 Digital SLR models,repparttar 144731 performance on these cameras has increased year on year withrepparttar 144732 latest Digital SLR cameras being quicker and faster than ever before. They have improved to such an extent that power up or start-up time is near instantaneous with virtually no lag time. “Lag time isrepparttar 144733 time between you pressingrepparttar 144734 shutter release button andrepparttar 144735 camera actually takingrepparttar 144736 shot”. This delay can vary quite a bit between different camera models and it is one ofrepparttar 144737 biggest drawbacks compared to a compact digital camera. The latest digital SLR cameras have virtually no lag times and react inrepparttar 144738 same way as conventional film cameras, even in burst mode. Compact digital cameras are catching up; howeverrepparttar 144739 difference is still significant. A lag time of ~0.5 seconds can result in you missingrepparttar 144740 heartbeat ofrepparttar 144741 moment and hence that potential great picture. Digital SLR camera also has a larger sensor versus a smaller sensor in a compact digital camera. This equates to higher sensitivity and less noise and results inrepparttar 144742 camera taking clearer pictures in low light. (They also have better autofocus speed in low light as well). A measure of sensitivity in a digital camera is ISO and a typical ISO range for a Digital SLR camera varies from ISO 100 – 1600 withrepparttar 144743 latter being more sensitive. The ISO range for a compact digital camera varies from ISO 50 – 400. In summary,repparttar 144744 higherrepparttar 144745 ISO rating,repparttar 144746 greaterrepparttar 144747 sensitivity andrepparttar 144748 betterrepparttar 144749 photo can be taken in low light.
