| contents | Filter is a very important circuit in the signal processing system. The latest technology in the field of telecommunications must have a series of filters on the system. Filters are also often found in telecommunications systems that use human voice as a source of information such as mobile phones. When recording human voices using a cell phone, the recorded sound is often mixed with noise because it is used in noisy environments, and the information recorded becomes unclear. This problem can be overcome by installing a filter that can pass the frequency range of human voice that is between 300 Hz to 3400 Hz, and in this experiment we are using an analog chebyshev bandpass filter. In this study, it was found that to pass a frequency bandwidth of 300 Hz to 3400 Hz required an order of 22 bandpass orders by arranging in series of 11 Delyannis and Friends bandpass filter circuits. Filter simulations designed in this study by using LTspice show that the filter is able to pass signals in the frequency range 300 Hz to 3400 Hz, and damped signals that have frequencies under the 300 Hz limit and above 3400 Hz according to the desired filter specifications. |
