Signal-to-noise ratio. It is also known as the signal-to-noise ratio, that is, the ratio of the voltage of the output signal of the amplifier to the noise voltage output at the same time, which is often expressed in decibels. The higher the signal-to-noise ratio of a device, the less noise it produces.
Generally speaking, the higher the signal-to-noise ratio, the smaller the noise mixed in the signal and the higher the sound quality of the sound playback, otherwise the opposite is true.
The signal-to-noise ratio should generally not be lower than 70db, and the signal-to-noise ratio of high-fidelity speakers should reach more than 110db.
English name of Token: SNR (Signal to Noise Ratio).
Signal-to-noise ratio - Concept Signal-to-noise ratioConcept of signal-to-noise ratioThe signal-to-noise ratio is the ratio of the normal sound signal played back by the speaker to the noise signal (power) when there is no signal. It is denoted by db. For example, the signal-to-noise ratio of a certain speaker is 80dB, that is, the output signal power is 80dB greater than the noise power.
The higher the signal-to-noise ratio, the less noise there is.
The simple definition of "noise" is: "the signals generated by the device itself during processing" that are independent of the input signal. For ***** devices, the signal-to-noise ratio is a relatively important parameter, which refers to the ratio between the maximum undistorted sound signal intensity and the noise intensity emitted at the same time by the sound source, which is called the signal-to-noise ratio, referred to as signal-to-noise ratio (signal-to-noise ratio), usually expressed in S n, and the unit is decibels (dB).

The signal-to-noise ratio, also known as signal-to-noise ratio, is the contrast between the strength of the useful components of the signal and the noise, and is often expressed by the number of decibels. A higher signal-to-noise ratio of a device indicates less noise it produces, and higher indicates less noise it produces.

The credit creation function is the most significant feature that distinguishes commercial banks from other financial institutions. Commercial banks issue loans on the basis of absorbing deposits, and on the basis of the circulation and transfer settlement of checks, loans can be converted into deposits, and in the case of deposits not being withdrawn, the funds of commercial banks are increased, and finally, the entire banking system can form derivative deposits that are several times the original deposits, which is the credit creation function of banks.
The two necessary conditions for commercial banks to carry out money creation are: they can operate deposit business and loan business, and money creation can only be carried out under the continuous cycle of these two businesses. If you can't engage in deposit business, you can't create money; If you cannot engage in loan business, you will not be able to provide funds for deposits to the public.
Two conditions are indispensable. Although other financial institutions have the business of raising funds and using funds, they cannot operate deposit business and loan business, and do not have the conditions for money creation, so they do not have the function of money creation.
The meaning of credit creation is manifested in two aspects: on the one hand, with the development of the credit system, commercial banks have created credit circulation tools that can replace money on the basis of bank credit, such as bank bills and checks.
This kind of credit circulation tool replaces the actual currency circulation, thus relatively expanding the means of circulation and payment, and expanding the amount of social credit. On the other hand, commercial banks can play an important role in the money supply mechanism by creating deposit money under the condition that checks are widely circulated and transfer and settlement are implemented.
In short, the mechanism or process of money creation in commercial bank deposits is that after the bank issues a loan to the deposit, the customer who receives the loan does not withdraw cash completely or even does not withdraw cash at all, but transfers it to his bank deposit account to make payment and use in the form of transferring deposits. In this way, a new deposit will be formed from the original deposit after the loan, which will increase the funds of the commercial banks**, and finally double the deposits of the entire banking system.

Beliefs can be material, such as money worship, hegemony, and so on. Faith is more embodied in spiritual life and is an ideology.
