The following describes filter types‚ what they do and how they perform. Along with definitions and detailed graphs‚ we are hopeful this information is both useful and informative. Filter Types Monolithic Crystal Filters 2 Quartz resonator internally coupled utilizing piezoelectric effect. Discrete Crystal Filter Single quartz resonator with external components utilizing the piezoelectric effect. Notch filters Crystal or Discrete component filter that passes all frequencies

cigarette filter as a source of glue. C. Hypothesis: Alternative- hypothesis: Cigarette filter is a good source in producing glue. Null- Hypothesis: Cigarette filter is not a good source in producing glue. D. Significance: Glue is very common used in homes‚ schools and offices. Many people just toss aside a cigarette filter and it can be recycled and used. Due to the expensiveness and unaffordable of some glue‚ many would prefer making home made glue. Glues from cigarette filter is affordable

FILTERS: Filters of some sort are essential to the operation of most electronic circuits. Filters and Signals: What Does a Filter Do? In circuit theory‚ a filter is an electrical network that alters the amplitude and/or phase characteristics of a signal with respect to frequency. Ideally‚ a filter will not add new frequencies to the input signal‚ nor will it change the component frequencies of that signal‚ but it will change the relative amplitudes of the various frequency components and/or
