Question

A system is sampling a high-frequency signal using an external 16-bit ADC connected to a 5. microcontroller using an SPI bus. The ADC returns a 16-bit sample every time that the SPI bus Poes active. The SPI bus is configured to send 16 bits at a time and runs with a 500,000 Hz clock Determine the maximum sample rate that can be achieved using the ADC connected to the microcontroller using this SPI bus. Assume that the clock must be inactive for the equivalent of one clock cycle between each transmission LO
