| The MCU also provides an 8-channel 10-bit analog-to-digital converter, as well as a 2-channel 10-bit Pulse Width Modulation (PWM) output that can be used as a digital-to-analog converter by connecting a low-pass filter. The AAF equalization circuit consists of a low-pass filter with a first-order frequency boost, a sample and hold, two comparators, a digital counter and some control logic, as shown in Figure 3. The accuracy of the estimate in this first step is governed by the bandwidths of the raw EMG signal and the low-pass filter used [6] and is limited. |
