I want to get the signal from the headphone jack of the mobile phone to drive a monostable circuitFrom left to right, the gate circuits are called Gate 1 , Gate 2 , Gate 3 , and Gate 4.
The monostable...
Now I need to make a tester to measure micro displacement, and the sensor I choose is a Hall sensor. The requirement is that the range is 1--2mm, and the accuracy is about 1um. I am a beginner, and I ...

As the whole equipment is becoming increasingly miniaturized and power-saving, low-dropout linear regulators (LDOs) with low power consumption are becoming the mainstream in the market for linear regu...[Details]
Overview
In recent years, the vigorous development of integrated circuits has created a huge space for the research and application of digital circuits. FPGA has low power consumption, high re...[Details]
With the continuous emergence of new technologies and the increasing complexity of DSP real-time systems, there are more and more different types of external devices. Writing drivers for these exte...[Details]
Introduction
The MAX2116 P1db data is measured at specific combinations of RF and baseband gain over the adjustable range of these two gains. These data can be used to select gain control se...[Details]
1. What is fading?
In terms of scope, fading can be roughly divided into three types: large area fading, small area fading and indoor fading. As shown in Figure 1, large area fading refers t...[Details]
Most
embedded
systems are powered from a 48V backplane. This voltage is typically stepped down to a lower intermediate bus voltage of 24V, 12V, or 5V to power the circuit board racks withi...[Details]
Abstract:
Using TMS320F2812 DSP chip as the control unit, without any gate control device control, the rich software resources of DSP 2812 are used to achieve equal precision measurement. A...[Details]
Abstract: This paper introduces the controller, interface, display principle and driving method of the handheld computer LCD display based on the SA1110 microprocessor. Combined with the HPC projec...[Details]
In the process of RF transceiver application, adjusting the processing gain (PG) of the direct sequence spread spectrum communication system (DSSS) can obtain excellent anti-noise performance, whic...[Details]
I hope my mobile phone has more functions, I hope my digital camera is smaller, I hope my Walkman can listen longer... Consumers are always full of expectations for the performance of portable electro...[Details]
Preface
In the application of PLL, DLL and CDR circuits, people generally require the output clock signal to have a 50% duty cycle so that data can be sampled at both the rising and fallin...[Details]
Portable products are generally powered by batteries. Due to cost and size considerations, there is a trend to reduce the number and size of batteries used in design. If the number of batteries is ...[Details]
With the continuous development of digital television, the demand for high-definition is imperative. H.264, as a new generation of compression standard, has a more complete algorithm than MPEG-2, ...[Details]
1 Introduction
In many communication systems, the base station usually sends a training sequence for the terminal to synchronize with the system. The synchronization here includes time syn...[Details]
The growing global interest in green power has added new variables to the design of power supplies and power adapters. Designers must not only traditionally consider the design specifications requi...[Details]
