What is Analog electronics: Definition and 14 Discussions

Analog electronics (American English: analog electronics) are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two levels. The term "analogue" describes the proportional relationship between a signal and a voltage or current that represents the signal. The word analogue is derived from the Greek word ανάλογος (analogos) meaning "proportional".

    I Analog TV reception in a spacecraft moving relative to the Earth

    During the Apollo 11 mission to the Moon there at least two occasions when the crew indicate they are watching live TV broadcasts from Earth. We know they originate from Earth because they are live TV transmissions that were received by network TV and recorded on video that is available in the...

    Minimum Frequency of FM Data / Catastrophic Error Scenario?

    Ever since I learned about FM something's been bugging me, which is that the PLL error correction acts on the encoded data, seeming to leave open the possibility of the shape of the data itself interfering with the PLL's interpretation of what the carrier frequency is. It seems dangerous to mix...

    Engineering Op-Amp circuit output analysis trouble

    THE ANSWER IS GIVEN: 6V, but according to me as the positive terminal is grounded the negative terminal will be virtually grounded (0V), from ohm's law (applying to the two series resistance) it is expected that Vo is 0V! I don't know where I am getting wrong!

    Other Any books on these topics in Analog electronics?

    In our fourth semester academic curriculum, we have a paper on Analog Electronics. (For those who don't know: I am studying UG physics major.) I have found some good lectures online that cover a part of the course, but I don't have any material for the rest of the topics. The following topics...

    Engineering Analog electronics (BJT circuit analysis)

    Homework Statement For beta = 100 and assuming ro is very large, what is the DC voltage at the collector? Homework Equations IB = IE(β+1) IC = β*IB The Attempt at a Solution Since IE = 0.5mA, IB = 0.0505 A Then, IC = 5.05 A (which doesn't feel right) VC is the same potential across the 30kΩ...

    [Paper choice] Numerical Mathematics or Analog Electronics and Circuit Analysis.

    I am a physics major and have to make a choice between either of these two papers. The numerical mathematics is at the equivalent to US senior level and the electronics paper is equivalent to US junior level. I'm quite interested in biophysics and/or medical physics for grad school but I'm not...

    Mathematical treatment of analog electronics

    Hello. I was wondering if anyone here could recommend a book on analog electronics that doesn't shy away from the math, but isn't too advanced for my level (electronics-wise, not math-wise). For reference, I've gone through Floyd's Electronics Fundamentals (although I don't necessarily...
