You can intilize your variable in an m file with an input of frequncy in hertz divide it by 2*pi, lets say foo = value/ (2*pi) and enter foo in the sinwave block – Novice_Developer Jun 9 '16 at 13:34 Thanks for the reply. But I know about that as well. I'm just wondering if this (rad/sec) can be changed to (Hz). changing frequency. The complex impedance measured is changing along with the frequency. The frequency sweep is usually in a wide range of frequency band. For example the bandwidth is from 1 Hz to 10 kHz. To measure the impedance, a load bank and a frequency response analyzer (FRA) connected to each other with the fuel cell is needed [5]. Jun 27, 2009 · By resetting the clock of simualtion from rising edge of the signal to falling edge of the reference signal you can measure the frequncy of the signal.

Experiment with the settings to move the cursors anywhere on the screen or measure the locations of other signals. You can move the cursors with the arrow keys and also snap them to either the nearest data point or screen pixel. Description of FR Measurement Techniques. An FR measurement compares the output levels of an audio device to known input levels. A basic FR measurement consists of two or three test tones: mid, high, and low. In this example you perform an audible range FR measurement by sweeping a sine wave from the lowest frequency in the range to the highest.
