Oscillator is defined as an electronic circuit which is designed to be a signal wave generator or generator of other periodical waves. Further, there are some basic forms of oscillator wave, which are 1) square wave, 2) triangle wave, 3) sawtooth wave, and 4) Sinusoida. Yet, each of the wave has its own characteristic. However, this research paper’s scope(More)
In this research, we design several prototypes of front end-devices for smart home applications, especially on mechanical aspect. We observed that there are several basic functions which can be explored and used to represent common mechanical home appliances. We use four representative mechanical functions: (1) solenoid is used for controlling door lock;(More)
Trans-impedance amplifier (TIA) are widely used for optical sensing applications (precision instrumentation) and optical communication, such as: fiber optic, IR communication and also Visible Light Communication (VLC). TIA convert the current (I) into voltage (V). Application TIA design depend of objectives requirement system, for high speed as well as(More)
Tool kit is one of learning media that have important role in engineering education, the author has been finished in developing tool kit with oscillator “LC circuit” topic. This oscillator can generate a sinusoidal wave with constant frequency and amplitude. With this tool kit wish the student can develop their skill and applicated in electrical,(More)
Communication is a means to send and deliver information and understanding from one to another. Yet, one of the purposes of communication is to deliver a message of feeling and the material usually used in communication is either question or assertion. Besides, images or pictures are a kind of non verbal communication that could represent thousands of(More)
