Design a switched capacitor circuit that could be used to synthesize a 100 k2 resistor where the high frequency band limit, of any signals passing through the equivalent synthesized resistor, is in the range expected from your audio band-limited smart phone. I will accept any reasonable number for what you consider the highest frequency for quality speech one could expect from your smart phone. Be sure you do not include the op amp. Your design should include: Well-labeled circuit diagram Design equations with key component values and an appropriate clock frequency. Clock waveforms .

Antenna Characteristics

The antenna is an important concept in the domain of electronics and communication engineering. An antenna forms an integral part of many commonly used devices such as wireless modems, routers, game controllers, mobile phones, bluetooth devices, and so on. In simple terms, any wireless communication makes use of antennas to serve the purpose. An antenna, also known by the term 'arial', is an electrical device that converts electrical signals into electromagnetic waves or electromagnetic waves into electrical signals. An antenna contains a transmission line usually made up of co-axial cable, it then receives the signals and converts them into electromagnetic waves, which are then transmitted via space into their required destination. A communication system essentially makes use of two antennas, a transmission antenna, which converts electrical signals into electromagnetic waves, and a receiving antenna, which receives the electromagnetic waves and converts them back into electrical signals.
