We study the effect of quantization on the performance of a scalar dynamical system. We provide an expression for calculation of the LQR cost of a dynamical system for a general quantizer. Using the high-rate approximation, we evaluate it for two commonly used quantizers: uniform and logarithmic. We also provide a lower bound on performance of the optimal quantizer based on entropy arguments and consider the case when the channel drops data packets stochastically.
