What is the action of a mercury barometer? Mercury barometers are primarily used for measuring atmospheric pressure. It is a device that consists of an upside-down tube filled with mercury that is in a vessel full of mercury. The atmosphere (or the air) pushes down on the mercury in the vessel, which in turn, pushes […]
What is the fundamental angular frequency?
What is the fundamental angular frequency? Explanation: The inverse of the fundamental time period is called fundamental frequency. If it is F, then 2πF is called the fundamental angular frequency ie it is a fundamental frequency in radians. So, LCM gives the time period as π. What are periodic signals? A periodic signal is one […]

What is called frequency?
What is called frequency? Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in hertz (Hz) which is equal to one event per second. What is meant by time […]
