Method for improving data transmission rate of electrocardio and electromyographic signal testing equipment

The invention provides a method for improving the data transmission rate of electrocardio and electromyographic signal testing equipment. According to the characteristic of continuous change of the electromyographic signals, the signal numerical value of each sampling point transmitted by the general electromyographic signal testing equipment is converted into the increment of the signal numerical value of each sampling point compared with the signal numerical value of the previous sampling point, so that the bit number of data can be greatly reduced, and under the condition that the transmission baud rate is not changed, the transmission efficiency is greatly improved. The data volume transmitted in unit time can be improved, so that the data transmission rate is improved. By adopting the method provided by the invention, the data rate of the communication channel between the lower computer and the upper computer of the electrocardio and myoelectricity tester can be greatly improved, the data transmission is
