A bridge has an upper frequency limit because above that frequency the measuement accuracy fails because of stray capacitance and inductance inside the bridge device.
MMF can stand for lots of things. What is MMF?
f=0.159/RC . where R and C are the feedback network of wien bridge
It is like a sine-wave, but in the cycle both halves have the same polarity. Alternate half-cycles are reversed in phase so that they are all the same way. The fundamental frequency in the waveform is double the supply frequency, making the design of the filter easier.
how to do scope and limitation
Yes. The resistance does depend on frequency. The reason is 'skin effect'. When an alternating current is passed through a conductor only a small portion of the conductor, usually called the skin depth carries the current. The value of skin depth is inversely proportional to frequency. As the frequency is increased, the skin depth decreases. But the value of ac resistance is directly proportional to frequency, or in other words, inversely proportional to skin depth. Thus, at higher frequencies, ac resistance is higher. This is the reason why we multiply the dc resistance by an empirical value 1.2 or 1.3 to calculate its ac equivalent.
The frequency domain cannot be infinite.
weins bridge
THe scope and limitation of science scope have only a reason to values but the limitation has not answer at all hahaha
it is not succeptible for high dc current
twice the input frequency
The answer depends on what you consider to be the limitations.
The three phase bridge rectifier has the highest ripple frequency. In a 60 Hz system, the ripple frequency would be 360 Hz. If it were a one phase bridge rectifier, the ripple frequency would be 120 Hz.
1.Amplitude 2.bandwidth 3.Noise 4.Frequency
Unintended consequences would be one reason.
A Wein Bridge Oscillator is a oscillator which is used for the measurement of Audio Frequency.
f = 1/(2πRC)
In a bridge circuit, balancing the equation independently of frequency ensures accurate measurements regardless of the input frequency. This is important for applications like strain gauges and temperature sensors, where changes in frequency could introduce errors in the measurements. Keeping the equation independent of frequency allows for consistent and reliable results.
