Document Summary
Purpose: to measure the time constant of typical rc circuits and study the correlations between time constants and frequency response, using the oscilloscope as a measuring device. Assembly: for all of the circuits in the manual a 1k ohm resistor and a . 1 f capacitor were used. For the first two diagrams a peak to peak 10v sine wave with varying frequencies was used. For #5 a 500hz square wave from 0v to 5vwas used. For this diagram we were asked to take the voltage reading at vout for various frequencies noted in the table below. Zc = -j (1/wc) = -j(1/1592) = -j999. 72 = -999. 72 -90 . For this diagram we were asked to take the voltage reading at vout for various frequencies noted in the table below. (hz) Determine the cutoff frequency for the highpass filter as in procedure 2. Zc = -j (1/wc) = -j(1/1592) = -j999. 72 =- 999. 72 -90 .
