91.3.1. Signal Connections and Ideal Model

In this case as I said that the input signal and output signal are say voltages. So, here we consider it is voltage here also it is voltage, so the signal here it is voltage and this is also voltage.

This chunk introduces the basic concept that both the input and output signals in the given model are voltages. Understanding that both signals are in the form of voltage is crucial because it sets the foundation for how these signals will be processed and manipulated in the feedback system.

Imagine you are looking at two streams of water (the input and output signals). If both streams are of the same type (for example, both are water), then you can manipulate them together in the same way, just like we do with voltages in an electronic circuit.

So, we do have parallel port. On the other hand if you see signal here they are voltages, so our intention is to use these two voltages to generate this S or v . These two signal sources they are connecting in series.

This chunk explains the concept of sampling and mixing in voltage signals. The text mentions that the output signal is sampled via a parallel connection while ensuring the two voltage sources that contribute to generating a signal S are connected in series. This highlights two crucial types of connections in the model: parallel sampling for the output and series mixing for generating the desired voltage.

Think of a DJ creating a new song by sampling sounds. The DJ 'samples' (or records) some music from one source (parallel connection) and then combines it with sounds from another source (series connection) to create a unique track. In our circuit, we sample and mix voltages in a similar creative way.

Assuming there is no loading effect... we have considered this ideal situation namely the resistance here it is ∞. So, I am keeping this is open so, R it is ∞. On the other hand output resistance here R , so that is equal to 0.

In this chunk, the text introduces the concept of ideal models in electronic circuits. It explains that for the analysis, we assume that the resistance at certain points is infinite and zero at others. This simplifies the model by eliminating loading effects, which can distort signals. These assumptions help in analyzing how the system behaves under ideal conditions.

Consider a traffic flow scenario where we want to test how traffic lights work without cars actually being there (ideal situation). By assuming no cars (loading effect), we can see how the traffic system would work in the best possible scenario before applying it to real conditions where cars do exist.

We said that the A is remaining A, we do not have to consider A′. On the other hand, R of this feedback network which is R′ which is we are assuming it is 0.

This portion discusses the relationship between the ideal model's parameters and how they remain unchanged under ideal conditions. It states that the overall gain 'A' of the system doesn't change despite the feedback introduced, as long as input resistance R' is assumed to be zero. These points reinforce the concept of maintaining stable and consistent feedback in circuit designs.

Think of a company that maintains its core values (A) regardless of shifts in the market (feedback). Just as the company's fundamental ethos does not change when external factors come into play, the circuit's gain remains constant under ideal conditions, simplifying our analysis.

So, we may say that shunt sampling and series mixing. To compress it typically we use this word and this word. So, alternatively this configuration it can be named as shunt series feedback system or you may say that here the signal it was voltage, so we can say that voltage series feedback.

This chunk addresses how configurations in electrical circuits are named based on the connections used. The system can be referred to as 'shunt series feedback' due to how the signals are sampled and mixed together. Understanding the naming conventions helps in recognizing and discussing these configurations in different contexts.

Imagine naming different types of sandwiches based on their ingredients and how they are made. A 'Layered Veggie Sandwich' may refer to one with various veggies layered neatly, while a 'Mixed Potato Salad Sandwich' highlights the mixing of potatoes. Similarly, the names in circuit configurations describe the connections used and how signals flow, making it easier to communicate about them.
