Abstract
This diploma project deals with the technology called the switched capacitors which is used in modern integrated circuits. This helps in reducing the error in the output frequency response of any type of filter which utilizes the SC technology. SC is an arrangement in the filter where the resistors is replaced with capacitors where it charges and discharges according to the input signal. In order to realize this technology MAXIM range of universal active filters are used to filter the input signal given by a microcontroller and tuned according to the preferences with SC and finally the output is verified.
