Experiment 1: Frequency-Domain and Time-Domain
Measurements on RC Networks
The purpose of this experiment is to provide a review of frequency-domain and time-domain measure-
ments on simple RC networks, in particular low-pass and high pass filters. In addition, use of the following
instruments is introduced or reviewed:
• Function Generator
• Digital Multimeter
• Network Analyzer
The only advance preparation for this experiment is to glance through the operating manual for any of
instruments listed above with which you are unfamiliar, and to read the overview of the HP 3577A Network
Analyzer contained in Appendix A.
Note the distinction in the sequel between
as a waveform, i.e. a function of time, and
as the ampli-
tude or rms value of a single-frequency sine wave (and similarly for
The low-pass and high-pass filters to be examined in this experiment are shown in Figure 1-1. In each
. Measure the value of R with the multimeter and the value of C with
the capacitance meter.
1. Obtain a 100Hz sine wave from the function generator, with a 2.828V peak-to-peak signal level. Check
the frequency and output signal level with the oscilloscope.
a. Make the final adjustment of the function generator output with the multimeter (on AC Volts) to
obtain a reading of 1Vrms. Verify the signal frequency using the counter.
b. Use the function generator output as
into the low-pass network. Connect the multimeter (still
set to AC Volts) to the output of the low-pass network and record its reading as the rms output
c. Without changing the output signal level, vary the sine wave frequency to
and finally to 100kHz. Record the rms output voltage
at each frequency using the multimeter.
d. Repeat th
