SO I RAN OUT OF GAS THE OTHER DAY

[brickhardmeat]

I don't trust that digital gas gauge.

The LB Yaris gauge is not digital...it's analog!

No, you are wrong again....since the LB Yaris gas gauge shows bars, these indicators are ANALOG, not DIGITAL...you wrongfully think that just because the display is an LCD, that it is digital...this is wrong thinking...for that gauge to be digital, it would have to show NUMBERS!

I have Master's in Electrical Engineering, by the way ;-)

wow so by your reasoning everything DIGITAL has to have numbers right? well the basis of DIGITAl is 1 and 0 and as an example a binary clock doesnt show numbers just bars/dots/lines. also most car makes still use analog inputs and convert the data into digital form. its called ADC and sampling

the gauge display is digital since its probably BCD coded to display the bars, the mechanism is analog im not arguing that , but the DISPLAY itself is digital, they dont turn off gradually, each bar comes on 1 or off 0, we could be sitting here arguing till we're blue in the face but until we see the schematic of the gauge display you and i could both be wrong or right. Im sure your familiar with the 7 segment decoder chip , also it can have an ADC to take the level mesurment and convert it into bar display.

I would agree. On and Off does indicate binary which is digital.
The analog reading is digitized into 8 bars.

BTW - I don't much care for the gauge either.

It's more like retro futuristic—I'd expect to see the gauge in a Delorian or something.

Oh shit.. Pavel IS BACK!!

Just because the bars have two states (off and on) does not make the fuel gage digital. The bars are in fact not linear in representing the same quantities of gas. The gage is in fact analog, otherwise if it were digital then each bar would represent the same quantity of fuel, which they do not. For example the first few bars turn off slower then the last few ;-)

You sure you didn't get your degree in a cereal box?

next time you feel like correcting someone read the post correctly , think about your reply for at least a week then post

Why is there so much argumentation on this subject? Why don't we just look at the definitions of analog and digital and see which one applies?

To simplify, analog refers to something that is measured continuously, or even better, referring to a measurement that is infinitely divisible. Digital refers to measurement in set, quantifiable states—think of the difference between the real number line and the set of whole numbers.

And digital also refers to a digital display (see definition 4).

So, the display is obviously digital by all applicable definitions. The measurement is given in set, quantifiable form: 8 distinct, non-divisible bars. How the internal mechanism measures gas I do not know. But if it's measured using any sort of continuously divisible means, like a pressure sensor/voltmeter, then it's analog. I'm guessing that's the case. If so, then it's an analog measurement, with the gathered information being converted to digital form for display, much like music being converted from analog to digital or a film photograph being scanned into a computer.

Can this argument be done now?

Ah, I just quoted the last person who was talking about it. I wasn't specifically directing my statements at you or anyone in particular, just getting the facts out there.

I also ran out of gas a few weeks back. I notice now that once I fill up the gas tank, the indicator will show 1 bar missing from the top. If I turn off the car and restart it, it sometimes show a full tank. Sometimes, it will not reset it. Anyone else experience this? Planning on bringing it in but have been too busy at work.

Thanks All.

The gas gauge does not show numbers. It does not show a quantity numerically. It is analog just like a clock with big and little hands. Our Yaris gas gauge shows levels of gas, and there for is qualitative, and NOT quantitative. The number of bars does not matter, nor if the gauge monitors the gas level continuously or not. The data on the gauge are bars, therfore the gauge is analog. For the gauge to be digital, it would have to show the gas quantity left in the tank in DIGITS!

The A/C thermostat in my parent's home is analog because the gage shows a pointer that points to the current temperature. However the A/C thermostat in my home is digital because it shows the current temperature in actual digits, for example 69.5F
