 Related Questions Latest Answer : as i think,basically there are 3 states in a signal: on state, off state, tri state ... Why we are using the bridge rectifier in most of the circuits instead of full wave rectifier eventhough the output of both are same? Latest Answer : Bridge rectifiers use transformer that do not employ a center tap, thereby permitting the use of smaller transformers. this saves space, cost and is more effecient. ... In wave guides TEM wave propagation is not exit, give the physical interpretation? What is the Tri State of a Signal? Latest Answer : In digital ciruit, the gate output can be only high or low. In highstate the output source current at a minimum voltage, greater than ~2.8V if load(fan out ) is proper. In low state it will sink current at max output voltage less than ~0.8V. ... What is the meaning of Tristate Signal in Electronics? Latest Answer : An active digital line in case of multiplexed buses has three states. high & low when controlled, and tristated when not controlled or when it is free to be used by other controller. this state where in it's level is not determinable or when it ... Why are using 4ma to 20ma for signal transfer. Why not 0 to 20ma? Latest Answer : You can detect when their is an open circuit. ... How does a Signal differ from a Wave Latest Answer : TUF factor is high ... What is the meaning of Tristate Signal in Electronics? Latest Answer : Tristate device is 3 terminal device & it has three states. They are logic 0, logic 1 & high impedance state or tristate. This device can be used as switch. For ON logic 0 or logic 1 (depending on active low or active high appl) OFF as high independence ... Why vestisial side band is used in TV Signal Transmission? Latest Answer : SSB is suitable for Audio transmission where low frequency components are neglible towards overall signal reception. For video transmission, where low frequency components are not negligible, SSB fails to clearly seperate the upper and lower side bands. ... Why do we convert Frequency Domain to Laplace Domain? Latest Answer : Frequency domain ----> deals with jw Laplace domain ----> deals with s, but s = (sigma) + ( jw )so with sigma = 0, laplace domain and frequency domain are the same. We convert time domain to either laplace domain or frequency domain to study various ...
