A feed through term in block diagram refers to an input signal that directly passes through a block without being affected by the block's internal operations. It is often denoted by a straight line connecting the input and output of a block.
A feed through term is different from other terms in a block diagram because it does not go through any mathematical operations or transformations within the block. It simply passes through the block and appears at the output unchanged.
Identifying feed through terms in a block diagram is important because it helps in understanding the overall function of the system. It also allows for the simplification of the block diagram, making it easier to analyze and design the system.
Some examples of blocks with feed through terms include gain blocks, integrator blocks, and summing blocks. These blocks do not have internal operations and simply pass the input signal to the output.
Yes, a feed through term can be eliminated from a block diagram by using a different block or by rearranging the blocks. This can help in simplifying the block diagram and reducing unnecessary calculations in the system.
