“What is the best filter that I should use?” is often the question asked by many. There exists two different types of Linear Time Invariant (LTI) filters from transfer function standpoint…

The author, Floyd M. Gardner an influential expert in the area of PLLs, has presented a good reference book that encompasses all the theoretical and mathematical concepts for the phase…

Tapped-delay line filters (basically FIR filters) are best to simulate multiple echoes originating from same source. Hence they can be used to model multipath scenarios. Choose frequency-flat or frequency selective: If the…

Generation of random variables with required probability distribution characteristic is of paramount importance in simulating a communication system. Here, I will demonstrate how we can generate a simple random variable, estimate &…
