求翻译：当单片机控制一组数据采样完毕后，通过单片机软件控制单相桥式PWM逆变电路和滤波电路产生正弦波，单片机软件实现井下数据的2ASK调制与发射。是什么意思？

When the microcontroller controls a set of data sampling is complete, single-chip software control by single-phase bridge PWM inverter circuit and filter circuit generates a sine wave, single-chip software 2ASK downhole data modulation and transmission.

When single chip control sampling has been completed, a group of data through single-chip phone software control single-phase bridge PWM inverter circuit and filtering circuits produced sine wave, single-chip phone software realization of downhole data 2 ASK modulation and fired.

After the monolithic integrated circuit controls a group of data sampling to finish, has the sine wave through the monolithic integrated circuit software control single-phase bridge type PWM inversion electric circuit and the filter circuit, the monolithic integrated circuit software realization min

When the microcontroller controls a set of sample data has been completed, by single-chip software-controlled PWM Inverter circuit with single and filter circuit produces a sine wave, SCM software implementation of underground 2ASK modulation and emission data.

After the one-chip computer controls a group of data to sample, software control single-phase bridge PWM against change circuit and strain unexpected turn of circuit emerge sinusoidal wave through one-chip computer, the software of one-chip computer realizes 2ASK modulation and transmission of the d
