### Angular frequency (Пү) - Questions and Answers in MR

• Angular frequency (Пү), also known as radial or circular frequency, measures angular displacement per unit time. Its units are therefore degrees (or radians) per second. Angular frequency (in radians) is larger than regular frequency (in Hz) by a factor of 2ПҖ: Пү = 2ПҖf. Hence, 1 Hz вүҲ 6.28 rad/sec
• Some motion is best characterized by the angular frequency (Пү). The angular frequency refers to the angular displacement per unit time and is calculated from the frequency with the equation Пү=2ПҖf. Key Terms. period: The duration of one cycle in a repeating event. angular frequency: The angular displacement per unit time

Solution: (a) Since k 0 2ПҖ, О» 2ПҖ k 2ПҖ 0 2ПҖ 10 m (b) up Пү k ПҖ 107 0 2ПҖ 5 107 m/s But up c Оөr Hence, Оөr c. Where: H(jПү) = transfer function at angular frequency Пү Пү = angular frequency and is equal to 2ПҖf Пү c = cutoff frequency expressed as an angular value and is equal to 2ПҖf c. Note: It does not matter whether Пү/Пүo or f/f c is used as it is purely a ratio of the two figures. If Пү which is 2ПҖf is used, then the factor 2ПҖ cancels out as it is on both the top and bottom of the fraction Пү is the angular frequency. Пү = 2ПҖf. f is the frequency of the sine wave. In DC circuits, the calculation of current, voltage and power is carried out using Ohm's law. Here the polarities of both voltage and current are assumed to be constant. In case of pure resistive AC circuits, the values of inductance and capacitance are negligible О©= Пү Пү c where Пүc is defined as the cutoff frequency for LD =2ПҖf C! maximum energy stored in the п¬Ғlter at f C power lost in the п¬Ғlter and to the external circuit Q =2ПҖf C! maximum energy stored in the п¬Ғlter at f C power lost in the п¬Ғlter The loaded Q is defined as A higher Q indicates a more selective filter.
