Logic circuit Ask for a detailed explanation, what is this logic circuit called?

This kind of wire is more common in real-world applications, and the question tests the understanding of the diode's conduction conditions.

To put it simply: ABC is connected to a diode, and VCC is a positive voltage. Then when ABC is low, the diode is turned on to ground, then F is equal to 0 potential. As long as any diode is turned on, f is 0, so it is an AND gate.

Exam skills: I really don't understand, so you can substitute the law:

Suppose it is an or gate, then a is high and b is low, but f is 0, and the answer a is wrong in the first place.

Suppose it is an NAND gate, a is high, b is low, then f is 0, and the answer c is also wrong.

In the same way, D is also wrong, then B remains

The nature of the diode is unidirectional, the on-voltage is, and the circuit in the diagram is called a "line-and" circuit, because as long as any input of a, b, and c is low, the diode is positively conducted, and the output f is clamped by the diode (low + logic low; F can output high only if a, b, c are all input high, which is the logical "and", f = a * b * c.

Select B.

The open-collector output (OC or OD) of the digital circuit can also be directly connected to the output for wiring and calculation.

This is the diode "AND-gate" circuit (b).

According to the different characteristics of logic functions, digital circuits can be divided into two categories, one is called combined logic circuit (referred to as combined circuit), and the other is called sequential logic circuit (referred to as sequential cavity attitude file circuit). The characteristic of the combinatorial logic circuit in the function of the chaotic logic is that the output at any time only depends on the input at that time, and has nothing to do with the original state of the cracked circuit.

This can only be understood and judged from the internal logic diagram of the decoder on the right. Y0 and y7 are 8 NAND gates with 3 inputs, and A, B, and C are 3 NAND gates. We know that the logical relationship between the input and output of this is that of the non-gate-based pure is Bo Xun:

0 out of 1, all 1 out of 0. It can be observed that when c, b, and a are all input to 0, the inversion of the three NAND gates just satisfies the logical requirement of y0 out 0, while the rest y1.

This is an XOR gate symbol with a switch-enabled chain-controlled chain. The g above represents the enable pin, and the lower 1, not 1, means that if the input is a high level and a low residual level, then the output is 1. Vertical defeat is pure, otherwise the output is low.

A logical circuit is a circuit that implements the logic operation and operation of digital signals based on the principle of pre-binary. Logic circuits are the basic building blocks of digital circuits. The so-called logic means that the state of the logic is true and false, which are represented by high and low levels, respectively.

Kieben's logic circuits have AND, or, and NOT gate circuits.

Logic circuits are the nickname for integrated chips.

To put it bluntly,,It's the most critical part of the mobile phone,The logic circuit can handle a variety of canopy training functions such as data stuffiness,For example, it's like a broken chain of human brains (hehe,,It's a bit serious)

It is a circuit designed with the switching characteristics of a transistor. Generally, the high level is 1 and the low level is 0, so binary is applied. Others are said on the second floor.

The basic logic gate circuits are AND gates, OR gates, NAND gates, and NAND gates, of which the most commonly used basic logic gate circuits are AND and gates.

Solution: 30 10 = 300 = 60 (cubic centimeters); Answer: The volume of these 5 goldfish is 60 li.

c=(a'b')'

A and B are first inverted and reversed, and then the and (trembling is multiplied) operation are carried out, and the result is inverted and output as C

To put it simply, a logic circuit is a digital circuit.

Three-way neutral line, that's fine.
