      +Angelica Morales Never say "just an associates". It takes hard work to get there and you should never think lesser of it. Besides, you might go on to get a higher degree later. Or you might work somewhere and make more many than many people that have higher degrees. :)

    Thank you so much for uploading the digital electronics series. I am studying electrical engineering at university, this series has been invaluable to me. By far the best online tutor for digital electronics on youtube.

    at time 15:32 on grey code, is the LSB being incremented by one? or is the last two bits increment by one?

    • @MovieHQ
      @MovieHQ  Год назад

      Grey code follows a very specific pattern. Only one bit at a time changes. This is unlike regular counting where multiple bits change sometimes.

  • @james77011
    @james77011 2 года назад

    On the encoders can u input the number 12 in decimal and get out an 8 bit BCD? ( 4 bits for the decimal number 1 and another 4 bits for the decimal number 2)

    • @MovieHQ
      @MovieHQ  2 года назад +1

      I honestly do not know. There might be a chip that does that. I only have used the very basic 4 bit BCD ones.

  • @TheArmando00
    @TheArmando00 7 лет назад

    On minute 5:15. It says that the out will be A > B if 85 >32. But on 35 > 31 he has to look to the other numbers inside of the 7485. Why?

  • @james77011
    @james77011 4 года назад

    Are u planning on making a video about grey code? I really didn't get it here. and i would love to understand grey code a little better. Or do u know of any nice videos on grey code?

    • @MovieHQ
      @MovieHQ  4 года назад +1

      I don't have plans to make one. Basically, grey code is used to represent data but only has one bit change for each count. For example, in binary when we go from 011 to 100 we have 3 bits change. In grey code, you would never have that. It is usually used to represent location data for an coded wheel. We used it in some old school robotics at one time. www.allaboutcircuits.com/technical-articles/gray-code-basics/

      @@MovieHQ so, the action of moving bits one at a time, is that similar to how a shift register work?

    • @MovieHQ
      @MovieHQ  4 года назад

      @@james77011 It is similar. For a multiplex/demux you would have serial data coming into the inputs and on the other end have serial data out.

    Great video! Are all encoders active low?

    • @MovieHQ
      @MovieHQ  9 лет назад

      Solomon TheCursedOne Thanks!! Not necessarily. You really need to look up the part number and see how that particular chip is set-up. They are all designed for different uses.

  • @fairyherb
    @fairyherb 6 лет назад

    Sir, could you explain for me why we have to use bubbles ( invertion) in chip 74 147 N. For example, we can represent input of 5 by 000010000 instead of 111101111. Thanks Sir,

    • @MovieHQ
      @MovieHQ  6 лет назад

      Thanks for watching! The active low (inverted) outputs are part of the chip itself. I did not add those. My best guess as to why they are active low is that we can use more current with a LOW than a HIGH.

    • @MovieHQ
      @MovieHQ  7 лет назад

      Sorry. Sometimes input and outputs are labeled as ABCD and sometimes A0 A1 A2 A3 etc. I just used them both. A0 is the same as A, A1 is B, A2 is C...

    Where will a comparator circuit be used in the real world?

    • @MovieHQ
      @MovieHQ  2 года назад +1

      You may want to compare 2 sets of sensors or data sets. Maybe you need to know if something is synchronized and you would compare those 2 signals. Pretty much anything.

  • @girishgirish007

    what are demultipleaxers ?

    • @MovieHQ
      @MovieHQ  7 лет назад

      They are on the opposite end of a multiplexer and work exactly the same just backwards. A single line into the chip with multiple outputs. Generally you synchronize the 2 together.

    @ time 14:01 is impedance defined as the opposition to current? 🤪🤷

    • @MovieHQ
      @MovieHQ  4 года назад +1

      Yes. For this circuits is is very high so in effect is disconnected.

    I find this topic amazingly boring. I understand what you say , but as soon as you move on to the next IC , I forget everything.
    I understood this whole video while I was watching this but I am still not sure of the functioning of an encoder and decoder'
    I hate this so much , I cant even...............

      Some of it is pretty boring. Unfortunately, many times one thing builds on the other. Just stuck with it.

    • @Leon-pn6rb
      @Leon-pn6rb 8 лет назад

      thanks for being nice. I get really frustrated when I dont understand something,simply because I can't focus on boring stuff.
