Teacher Li and Mr. Zheng are classmates, so they are very good. Naturally, I am lucky enough to get guidance from my classmates. Instructor Li and instructor Zheng gave me the training solution: learn from the operational amplifier first. So I re

What we need is a meaningful "input signal". We need to regard the two inputs as "whole ". Just like in Junior High School, the plane coordinates must be expressed by X and Y, while in high school or university, only one "Number" V is used, but this V is composed of X, "vector" composed of two numbers of y "...... The common mode and differential mode are the attributes of the "input signal". The differential input can be expressedVi = (vi +, Vi -)It can also be expressed Vi = (Vic, VID) C I

Active speakers and passive speakers: Computer speakers are mainly divided into two types of speakers, active speakers and passive speakers. The way to distinguish these two speakers is simple. Active speaker is built with a small power amplifier, directly through the speaker line plugged into the computer's microphone interface, and then the power can be connected to work properly. Passive speakers are generally mainly some large speakers or some ol

1. How to determine whether a basic amplification circuit is a common-base, co-injection or a common set? Remove the input, the output side, the rest is the common end. The following figure: The UI is connected to the base pole, and the UO is the common collector. 2. Basic Amplification Circuit: 2-1. Co-emitting minimal signal amplifier Function: Amplify the small amplitude voltage signal Working principle: Q1 is connected to the common-injection

information resources. So far, China's small user market is still in its infancy in the Construction of Integrated Wiring, bringing a broad market to the Integrated Wiring market. Home users have their own uniqueness. Personalized and differentiated requirements include multiple indoor systems, such as optical devices, power grids, telephone voice networks, and IPTV, at the same time, it will promote the requirements of small users for Integrated Wiring and the future development of integrated

Integrated Wiring System is the most basic system in smart buildings in modern society. At present, the information industry is developing rapidly, and the importance of networks has been deeply imprinted in people's minds, networks have become an irreplaceable part of our lives. For the most important hardware supporting the network, the performance of the integrated wiring system directly affects the transmission performance of the network. In the integrated wiring system, only the most rigoro

OM3 optical fiber testing method in compliance with ISO/IEC 11801 and EIA/TIA 2017-aaac-DMD Testing Problem: Is it necessary to verify that the 50 μm laser-optimized Optical Fiber meets the OM3 Specification through a DMD test? Answer: Yes. The requirements for testing methods are clearly defined in the requirements for OM3 optical fiber at 850nm with a 2000 MHz-km effective mode bandwidth of 50 µm optical fiber. The following points can fully demonst

dBrn, data with a maximum bandwidth of 155.6 bps can be transmitted at 76.8 kHz. The operating voltage range of nRF903 can be from 2.7V ~ 3.3 V, the consumption of the standby current is 600 laA, and the consumption of the low-power mode current is only 1 uA, which can meet the requirements of low-power devices. The nRF903 has multiple channels (a maximum of 170 channels). It is suitable for the use of frequency hopping protocol in special scenarios that require multi-channel operations. The an

mode to a specific part of the house. These antennas are not perfect-there are always some leaks at the rear of the antenna-but such leaks can actually become an advantage to provide connections to the equipment behind the antenna. For example, I place routers and antennas around 8 feet away from one end of a long house. My main work area is at the left rear of the antenna, but I still have a good connection effect in this area. In my configuration, I used a pair of Hawking Technologies Company

faster than before.2. Input is filtered first through R3 and C3,C4, and the output of the Zener diode is filtered through R4 and C5.3. Large capacitance C1 filter out most of the high-frequency components, so that they are not amplified by the error amplifier, thereby reducing the amplifier bandwidth, improve system stability.The performance of this circuit goes beyond the ordinary LM317, because the LM317

polypropylene film DC capacitor. Using metallic polypropylene film as medium and electrode, one-way extraction is encapsulated with flame retardant insulation material, which has excellent electrical performance, good reliability, low loss and good self-healing performance. Purpose: This product is widely used for DC pulse, pulse, and AC pressure in instruments, instruments, televisions, radios, and household appliances. It is particularly suitable for various types of energy-saving lamps and e

Capacitors are almost indispensable energy storage components in electronic circuits. They have the characteristics of isolating DC, Connecting AC, and blocking low frequency. It is widely used in coupling, isolation, bypass, filtering, tuning, energy conversion, automatic control, and other circuits. Familiarity with the name and meaning of capacitors in different circuits helps us understand the electronic circuit diagram. 1. The filter capacitor is connected between the positive and negative

is actually two division of power, and the division of Signal power and noise power is the SNR. For example: 30dBm-0dBm = 1000MW/1MW = =30db. DBM Plus dbm is actually two power multiplication without physical meaning.DB in the field of electronic engineering, the amplifier gain is used in db (decibel). The ratio of the amplifier output to the input is magnification, in units of "times", such as 10 times-
