Consider a single input single output discrete-time system with x[n] as input and y[n] as output, where the two are related as $$y\left[ n \right] = \left\{ {\matrix{ {n\left| {x\left[ n \right]} \right|,} & {{\rm{for}}\,0 \le n \le 10} \cr {x\left[ n \right] - x\left[ {n - 1} \right],} & {{\rm{otherwise}}} \cr } } \right.$$ Which one of the following statements is true about the system? An 8-bit microcontroller has an external RAM with the memory map from 8000H to 9FFFH. The number of bytes this RAM can store is Which new modulation technique is used by EDGE? If the base current of a BJT is 250 µA and emitter is 15 mA, then the common base current gain will be A continuous time LTI system is described by $$\frac{{{d^2}y\left( t \right)}}{{d{t^2}}} + 4\frac{{dy\left( t \right)}}{{dt}} + 3y\left( t \right) = 2\frac{{dx\left( t \right)}}{{dt}} + 4x\left( t \right)$$ Assuming zero initial conditions, the response y(t) of the above system for the input x(t) = e -2t u(t) is given by
