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

In the fume hood‚ approximately 2g of Ca(OH)2 was dumped from a vail into a 250ml beaker. To avoid any left-over Ca(OH)2 inside the vail‚ certain amount of distill water wad added to it‚ and the vail was shook several times after the lid was closed. Pouring the solution in the vail into the beaker‚ and add distill water until it reached the 100ml line. Then‚ the beaker was put on top of a magnetic stir with a magnetic stir bar placed in it.
