Energy harvesting is the process of collecting of energy from an array of environmental sources, both natural and artificial, most of which is otherwise wasted. These myriad forms of energy include any of those sources through which we can extract electrical current to power any number of low-power devices. The...
Radio Frequency Modulation Made Easy
Modulation is a technique that changes the characteristics of the carrier frequency in accordance to the input signal . Figure 1.1 shows the conceptual block diagram of a modern wireless communication system. As shown in the figure, modulation is performed at the transmit side and demodulation is performed at...
