critical frequency meaning in Hindi

Examples

1. For oblique incidence, the critical frequency becomes larger.
2. where the critical frequency is the highest frequency reflected for a signal propagating directly upward.
3. The amplifier will oscillate if it has a gain of one or more at this critical frequency.
4. The critical frequency of torsional vibration will change if weights of con-rods, pistons and crank counterweights are changed.
5. A family of sinusoids at the critical frequency, all having the same sample sequences of alternating + 1 and  1.
6. The critical frequency is the limiting frequency at or below which a radio wave is reflected by an ionospheric layer at vertical incidence.
7. It reflects normal-incident frequencies at or below the critical frequency ( approximately 10 MHz ) and partially absorbs waves of higher frequency.
8. If operated below critical frequency, heating efficiency is reduced because eddy currents from either side of the workpiece impinge upon one another and cancel out.
9. Since the cost of induction power supplies increase with frequency, supplies are often optimized to achieve a critical frequency at which a / d = 4.
10. He discovered that the layer could be penetrated by waves above a certain frequency and that this critical frequency could be used to calculate the electron density in the layer.
