check filter theory as shown in the college communications textbook. The pre-engineers are going to build a Narrow Band Pass Filter to compare theory with designed circuit behavior. By doing this the students will be able to better understand the theory based calculations and build hard wired circuits. When designing a band-pass filter‚ the parameters of interest are the gain at the mid frequency and the quality factor which represents the quality of the band-pass filter. A band-pass filter is one

low-pass filter is an electronic filter that passes low-frequency signals and attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. It implemented using a resistor and a capacitor. The actual amount of attenuation for each frequency varies from filter to filter. A low-pass filter is the opposite of a high-pass filter. The below circuit diagram illustrates a simple ’RC’ low-pass filter. The range of frequencies passed by a low pass filter within a

used in the experiment with hydrochloric acid (HCL) then followed with distilled water (H₂O). Then‚ prepared the saturated calcium hydroxide (Ca (OH) ₂) solution into a filter funnel and filter paper over a second conical flask. Pour 100.00mL of saturated Ca (OH)₂ solution into a beaker and pour the solution through the filter paper by flowing the solution through a glass rod. After that‚ use a thermometer to measure the temperature of the solution obtained in the conical flask. Fill 29.00mL of HCL

dissolved. The total volume of water used was recorded. The black solid that remain in the dissolved mixture was the impurity. 2. A filter was prepared by placing a fluted filter paper in a 3 inch funnel. The funnel was placed onto a 100mL beaker with 5mL of water at the bottom. The filter paper was moistened. The water was heated to preheat the filter with steam. The solution prepared in step 1 was filtered. 3. A watch glass was placed over the beaker that contained the filtrate and

Add crucible contents to a beaker then add 200 mL water and 125 mL of solution and stir. 5. Position filter paper in the funnel‚ drain water into another beaker. 6. Transfer the precipitated material to the flask‚ allow the funnel to drain. 7. Use a microspatula to school the material and set in the drying oven‚ allow it to cool. 8. Weigh and record the mass of the filter paper‚ repeat until the mass does not change. Pre Lab Questions: 1. 2. 3. 4. 5. Data Tables:
