[font=微软雅黑][size=6][color=#006400]How do you buy components? We are a small place, I don't know where to buy them, usually I go to Taobao. Can you recommend a good seller, there are too many, it's har...
Hey guys, there is a circuit for AC zero-crossing detection. I don't understand how the transistor is turned on in this circuit, and where the voltage at the B pole of the transistor comes from. Thank...
I started to use TI's DSP: 2812 for the first time in September this year, and made an audio processing system (just a few simple filters). The preliminary development has been basically completed tod...
I have read some books and have a general understanding of a bunch of concepts. I want to build something, but I don't know what the learning curve is. Could you please give me some advice on which dr...
UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]
Today's portable medical devices allow patients to diagnose and treat themselves, move around freely, and even use the devices when they are out and about. To achieve the "easy to carry" feature, po...[Details]
In today's society, heart disease has seriously affected people's life safety. Many patients with sudden heart attacks are threatened because they cannot get timely treatment. Traditional ECG monito...[Details]
Currently, it is impossible to dynamically obtain patient information in medical monitoring. Once the patient's condition worsens, emergency treatment cannot be implemented in the first place, and the...[Details]
