400 Hz

Backlight LCD Touch Screen C DES Integrated Analog Front End SER Input Low Pass Buffer (DC) Filter Wireless ZigBee® Bluetooth ADC High Pass Filter Micro- Controller ADC Wired: USB RS232 Ref Converter Micro- Processor (resistive) 10/100 Ethernet Pace Detection RLD Core Temp Sense and /O Power Lead Off Detection Logic DSP/Video Low Noise Power Human Body Plug Level Shift Green Mode AC/DC Supply Management Battery Battery Protection AC Line DDR Power8 LEGEND Logic Processor Power ADC/DAC Interface

Explanation / Answer

1) D-Low pass filter

2)H- Microprocessor

3) A- High pass filter

5)formula: (1/2)v

v=200 Hz

so Nyquist frequency would be (200/2)=100 Hz
