Abstract:
Oscilloscope and spectrum analyzer are the devices used to study different characteristics of the electronic signals. The available devices are two separate devices as oscilloscope and spectrum analyzer with a lot components common in these two devices. In this project both devices are combined as one device using the same hardware for both functionalities and using software to perform the required calculations. It is achieved by using analog to digital converter (ADC) to convert the analog signal into digital data. After that data is sent by Bluetooth to an android device where it is processed. It is plotted in time domain for the use of oscilloscope and for spectrum analyzer the data is converted in frequency domain by taking fast Fourier transform (FFT). Other required calculations are performed in the app so less hardware is used to perform these two functions.
