Figure 4. High pass filter Configure the waveform generator on the oscilloscope with following settings: Waveform = Sine Frequency = 1Hz, 10Hz, 100Hz, 1KHz, 10KHz, 100KHz and 1MHz Amplitude = 3V p-p Offset = 0V Connect the waveform generator output to the input of high pass filter. Connect channel 1 input (X) of the oscilloscope to the output of high pass filter and connect channel 2 input (Y) of the oscilloscope to the input of high pass filter. Measure V1 and V2 on the input and output of high pass filter by using the measurement function on the oscilloscope. It is more suitable to use AC to measure V1 and V2. In your lab report: Fill the table below: Gain (dB) Frequency (Hz) V1 (Volt) V2 (Volt) (G = dB) 1 10 100 1K 10K 100K 1M Plot the Frequency Response curve using semi log graph or use Excel to plot the graph. Explain why the gain of high pass filter drop significantly at very high frequency. Adjust the frequency of Wave Gen on the oscilloscope to find out the Corner frequencies of high pass filter, and . Where is the Corner frequency at lower frequency range and is the Corner frequency at higher frequency range. The Corner frequency is defined as the frequency at V2/V1 = 0.707. Measure the Corner frequency of this high pass filter found
