What restricts the ability to set a PWM signal with a frequency of 40 MHz and a resolution of 16 bits simultaneously?
What restricts the ability to set a PWM signal with a frequency of 40 MHz and a resolution of 16 bits simultaneously?
- The duty cycle variation
- The CPU clock speed
- The PWM wave slicing mechanism
- The clock source limitation (correct)
Why can't we generate a PWM wave faster than our clock allows?
Why can't we generate a PWM wave faster than our clock allows?
- Due to clock synchronization issues
- Because of the digital-to-analog conversion process
- Limitation imposed by the clock frequency (correct)
- Interference from other signals
How does the resolution of a PWM signal relate to the CPU clock speed?
How does the resolution of a PWM signal relate to the CPU clock speed?
- Resolution decreases with an increase in duty cycle
- Resolution is proportional to the PWM frequency
- Resolution depends on the number of slices per period
- Resolution requires a CPU clock running at PWM_freq * 2^PWM_resolution (correct)
