From: http://www.chinakong.com/forum/disp.asp? Id = 41310 Basic Principle of stepper motor 1. stepper motor is an open-loop control component that converts an electrical pulse signal into an angle displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and is not affected by the load c

of encoder extracts a set of parameters, which are sent to the receiver to export the speech to generate a pattern. Audio quality is not good enough. The hybrid encoder integrates the strengths of the waveform encoder and sound generator. Waveform encoder 2.1 Waveform encoder design is often independent of the signal. Therefore, it is applicable to the encoding of various signals, not limited to speech. 1. Time Domain Encoding A) PCM: pulse co

The zero crossing detection method is the function of the comparator. It can convert a sine wave of a certain frequency into a square wave or a pulse wave. This is necessary in the test frequency and other places, because FPGA only recognizes the edge, but does not recognize the sine wave. The algorithm is divided into two parts: the determination of the zero point and the generation of the pulse wave. Wh

Look at multi-core resources rationally and avoid wasting money when purchasing products. The original article is as follows: Multi-core is not equal to high performance The increase in the number of cores does not mean that the computing eff

find. However, in some cases, it is difficult to locate the obstacle location from the abnormal phenomenon on the route. In this case, the distance between the obstacle point and the test point must be measured based on OTDR, and the original test data must be checked, find out the block where the obstacle point is located, and then accurately measure the ground distance between the points through necessary conversion until the specific location of the obstacle point is found. However, the obst

The power frequency machine is a traditional X-ray equipment that uses 50Hz AC as the power supply of High Voltage Generators. We know that the composition of X-ray machine (or X-ray equipment) can be roughly divided into two parts: X-ray Generator (X-ray source) and auxiliary equipment. The following discussion will confuse the x-ray machine with the X-ray generator without distinction. High-voltage power supplies of power frequency X-ray machines are generally in the form of single-phase self

on the number of bytes sent each time. The first byte following the start condition should contain the address field. If the I2C bus operation is in host mode, the host sends the address domain. Each word segment should be followed by an ACK. MSB, the highest valid bits of the serial data and address, should be sent first. Send Response Signal To complete one-byte transmission, the receiver sends an ACK to the sender. The response pulse is generated

Although the advantages of a fully digital feedback path is impressive-including elimination of temperature and comp Onent-tolerance problems in the Error-amplifier/loop filter, and the ability to switch the response characteristics on the Fly-limitations still exist to the this design. These limitations is primarily in the pulse-frequency restrictions imposed by the purely digital PWM. (Remember a PWM peripheral with a resolution of 8 bits

" p191 has a routine;the defect of the scheme: a. If the delay is too short, it is possible to have a jitter time of two samples, which may cause false positives;B. If the delay is too long, the key transformation may not be detected(2) Continuous samplingThe principle of continuous sampling is that when a key is detected at a certain level (such as ' 0 '), the level of the key is continuously detected in the following n clock cycles, and if it remains constant, the level value of the key (such

resistor selection should be within the allowable range of last stage transistor power dissipation, and experienced designers will not choose 1 ohm resistor as pull-up resistor when using logic chip. In the pulse of the rising edge of the power supply through the pull-up passive resistance to charge the load, it is apparent that the smaller the resistance rise time is shorter, in the pulse of the falling e

. Ensure that the contact resistance is minimized, and the signal of each relay is measured normally at the disconnected block position on the side of the programmable switch, but the disconnection phenomenon has not improved. I speculate whether it is because the caller uses a portrait phone that can only be used for pulse dialing and cannot send dual-audio signals). However, I carefully analyze and query the local post office that is prone to discon

After the continuation is complete, the switch remains connected until the party that detects the communication hangs up. The part of the conversation is to use
