    Just an add-on to the above statement: "Nowadays, a sound card can have a sampling rate of up to 192 kHz, a bandwidth of 10Hz~50kHz, and a bit depth of 24 bit." In fact, quite a lot sound cards support (input & output) frequencies down to 1 Hz or even below that.

    PC capacitor meter

    1.  Two input channels of the sound card must be used, one to capture the signal from the DUT (in your case, a capacitor), the other to capture the signal directly from the sound card output channel. By comparing these two signals, the phase shift introduced by the DUT can be obtained. This...

    The amplitude accuracy depends on the quality of the sound card and, of course, the frequency of the signal under test. There are quite a few parameters that can be used to characterize the analogue accuracy of a sound card, such as: Frequency response, THD, THD+N, dynamic range, noise...

    Hi, indulis, The sampling rate accuracy is determined FULLY by sound card hardware.  A quartz on the sound card generates the reference clock. The accuracy of this reference is 0.00x% typically for an ordinary sound card. For example, a 0.003%'s inaccuracy in a sampling rate of 44100 Hz means...

    Hi, indulis As indicated above, "The actual frequency output accuracy will depend on how accurate the sound card's sampling rate is" Typically, the inaccuracy of sampling rate is in the order of 0.00x% for an ordinary sound card.

    Hi, Zeppelin, Theoretically, there is no error in the output frequency as long as it is lower than the Nyquist frequency (i.e. half of the sampling frequency). The actual frequency output accuracy will depend on how accurate the sound card's sampling rate is. Also, the software GUI only...
