A Block diagram is defined as a major flowchart used in the engineering sector. It is generally used while designing new systems or modifying the existing ones. The major advantage of a block diagram is that it helps users easily identify the bottlenecks in the system. Like a circuit diagram, a block diagram does not show the connection in detail but gives a rough idea of what the process is. Different shapes are used to create a block diagram. And the lines connect the blocks, representing the connection between the blocks. Through the circuit block diagram, let's understand the steps and processes involved in detail.

1. Understanding Circuit Block Diagram

While the block diagram usually consists of different shapes such as rectangles, triangles, and circles, their namings represent the component. The lines connecting the boxes show the relationship between them, and the arrows show the direction of flow or the supply.

The data is fed to the digital modulation system, which alters the transmittable signal based on the information in a message signal. Here, it outputs the complex envelope of the modulated signal.
The output from the digital modulation system is passed to the D/A system, where it is converted to the analog form.
The analog output is passed to the amplifier, where the signal's amplitude is increased.
The output from the digital modulation system is also passed to the oscillator, which then passes it to the digital demodulator.
The signal output from the demodulator represents a sound, image, or binary data.
The filtration process is done, and then the signal is again converted to an analog signal using the D/A system.

3. Important Tips to Consider While Creating Circuit Block Diagram
Make the block and circuit easy to understand through the proper arrangement of components.
Use minimal and functional blocks throughout the circuit design.
Through arrows, show the direction of the current flow and power supply.
Divide the circuit into different sets and connect them.
Place enough texts and specify the values in the circuit block diagram.


Block diagrams are used to understand complete circuits by breaking them down into smaller sections or blocks. Each block performs a particular function, and the block diagram shows how they are connected. Follow the tips mentioned while creating the circuit block diagram. They will help with debugging, simulation, referencing, and much more. It is recommended to use EdrawMax Online to create Circuit Block diagrams. The free electric circuit diagram maker offers free symbols that ease your efforts in creating the technical diagrams.
