Given a network of four microcontrollers with the following oscillators: f_1 = 4 MHz plusminus 10PPM F_2 = 4 MHz plusminus 100PPM F_3 = 4 MHz plusminus 120PPM F_4= 4 MHz plusminus 50PPM Given a maximum allowable offset (precision) of 4.5 middot 10^-4 sex/sec what is the maximum resynchronization interval that is required? What is meant by the \"Convergence Function\"?

Solution

a)

b) Convergence Function:

Considering Uniform convergence theorem. If (f_n) is a sequence ofcontinous functions of all of which are defined on the interval I which converges uniformly towards the function f on an interval I, then f is continuous on I as well.

similarly in case of microcontrollers ,for amicrocontroller engineer to consider a DSP or for a DSP engineer to use a microcontroler , three strict criteria must met,those are: price/performance, peripherals and development tool quality.
