Unformatted text preview: waveform had the least amount of distortion. Then I measured and recorded the frequency =145.5Hz 3. Replace C 1 and C 2 with 0.22 with 0.22 F. Frequency =71.84Hz 4. Replace C 1 and C 2 with 0.47 with 0.22 F. Frequency =33Hz 5. Replace R 1 and R 2 with 1K. a. Replace C 1 and C 2 with 0.22 with 0.22 F. Frequency=733.7Hz b. Replace C 1 and C 2 with 0.47 with 0.22 F. Frequency= 334.9Hz...
