ANALOG AND DIGITAL ELECTRONICS, image, image, image, image, image, image,…

- - - - Most of the fundamental electronics (resistors, capacitors, inductors, diodes, transistor and operational amplifiers) are all inherently analog.
      - Circuits bulit with a combination of solely these components are usually analog
      - Example analog circuit
        
        Analog circuits are usually complex combinations of op amps, resistors, caps, and other foundational electronic components. This is an example of a class B analog audio amplifier.
        
        Analog circuits can be very elegant designs with many components, or they can be very simple, like two resistors combining to make a voltage divider.
        
        In general, though, analog circuits are much more difficult to design than those which accomplish the same task digitally.
        
        It takes a special kind of analog circuit wizard to design an analog radio receiver, or an analog battery charger; digital components exist to make those designs much simpler
    - - Data transmission using digital systems
        
        The digital system send the data in the form of packets of digital codes, thus we can encode and decode them in various formats and codes
        
        Data encryption is also possible in the digital systems, hence the data transmission is more secure and can be manipulated in many formats
        
        Digital systems are much advantages in communications
      - Digital electronic safe box
        
        Electronic digital safe is perfect for securely storing your jewellery, valuables and confidential paper work.
        
        It features an easy to set electronic code with floor or wall mounting.
        
        There is also a digital lock, incorrect password alarm and two back up keys. There is a cash box with tray to keep your valuables and coin in and a carrying handle for your convenience
      - Registers
        
        A register is made out of multiple flip-flops connected to each other used to store multiple bits of data.
        
        If we have ‘n’ flip-flops, we can store ‘n’ bits of data
      - Shift register
        
        A shift register is a sequential circuit which stores the data and shifts it towards the output on every clock cycle.
      - Microprocessors
        
        a microprocessor, sometimes called a logic chip is a computer processor pn a microchip
        
        The microprocessor contains all or most of the central processing unit (CPU) functions and is the “engine” that goes into motion when you turn your computer on
