SNR is defined as the ratio of the output signal voltage level to the output noise level. It is usually represented in decibels (dBs) and calculated with the following formula. For example if the output signal amplitude is 1V(RMS) and the output noise amplitude is 1mV(RMS), then the SN...
图中,右上坐标系的横坐标表述真实输入信号(Input voltage),纵坐标(左)表示 ADC 量化信号(Quantized voltage),纵坐标(右)表示 ADC 转化后的二进制代码(Output code)。右下坐标系表示误差(Error)。 2-bit 的 ADC 分辨率很低,所以很容易看出误差。比如,当输入电压为 0V,输出二进制为 00 ,这个代码代表的是 0.6...
Q2, Now we use internal reference voltage 1.5V, and it is 16bit ADC, and the chip convert differential analog input into digital. My question is that,how to calculate differential into the digital, such as -Volt per bit, VPB = 1.5/65536; ...
However, this Design Idea presents a solution to the problem. Given the microcontroller’s power operating-voltage source, VDD, use the following simple formula to obtain the hex-code value corresponding to an identified input-analog-voltage level: VIN/(VDD/255)=result value="hex" code (see ...
Part Number: MSP430FR5994 Hi, At work we're developing a device which uses the MSP430FR5994 MCU to collect some telemetry data regarding the power bus (voltage
float voltage = (float(val)/1024) * 3.6; //formulae to convert the ADC value to voltage 您可能会对线浮点数 (val) 感到困惑。这用于将变量 “val” 从 int 数据类型转换为 “float” 数据类型。这种转换是必需的,因为只有当我们在浮点数中得到 val/1024 的结果时,我们才能将其乘以 3.6。如果以整数...
