Do reactive component of impedance dissipate power?
The reactive part dissipates no power because in a reactor the current is 90 degrees out of phase with the voltage. The effect of this is that any power that leaves the generator on one quarter-cycle comes back to the generator on the next. The net power is zero.
Which analog modulation scheme requires minimum transmitted power and minimum channel bandwidth?
ssb modulation scheme
What are the advantages of transistor-transistor logic?
Transistor-transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors. It is called transistor-transistor logic because both the logic gating function and the amplifying function are done by transistors.To know about the advantages of TTL logic family, one should have a basic idea about RTL, DTL etc. Diode logic (DL) uses diodes to implement logical functions like AND and OR. But the disadvantage is that it can not perform NOT operation. As AND and OR are not complete functions by themselves, they can not perform several logic functions without NOT. Hence, there was a need for some device which can perform a NOT function as diodes can not. That device is a transistor. Then came the DTL which uses a transistor along with diodes. As a transistor can act as an inverter, NAND (NOT-AND) & NOR (NOT-OR) operations can be performed. But this logic uses several diodes which will slow down its operation. Due to the delay offered by them, the logic levels may sometimes change i. e. 0 t0 1 or 1 to 0. Then came TTL. This logic uses a multi emitter transistor, a transistor with many emitter terminals. As every emitter is nothing but a diode, this logic eliminates the use of all diodes. This is the major advantage. As transistor becomes ON and OFF much rapidly than a diode, switching time will be faster.TTL, or Transistor-transistor logic replaced resistor-transistor logic, and used much less power. The TTL family is very fast and reliable, and newer faster, less power-consuming, etc. types are always being developed.ANSWER: ONE WORD SPEED
What is definition of Programmable Logic Controller?

Which logic family dissipates minimum power?
Cmos logic family, because it has no resistors attached who consume active power.
Which logic family has lowest power dissipation?
cmos
What are the disadvantages of TTL logic family?
Briefly, TTL uses more power than more modern families.
Term used to describe how much heat a circuit dissipates?
Power dissipation.
What term is used to describe how much heat a circut dissipates?
The term used to describe how much heat a circuit dissipates is "power dissipation." It refers to the amount of power that is converted into heat as the circuit operates, usually measured in watts.
What is the figure of merit of logic family?
A figure of merit correlated with the energyefficiency of a device. It can be calculated by the product of propagation delay time with power dissipation.
What is the figure of merit inic logic family?
A figure of merit correlated with the energyefficiency of a device. It can be calculated by the product of propagation delay time with power dissipation.
What is interference between ic ttl and cmos?
Solution: Characteristics of CMOS logic: 1. Dissipates low power: The power dissipation is dependent on the power supply voltage, frequency, output load, and input rise time. At 1 MHz and 50 pF load, the power dissipation is typically 10 nW per gate. 2. Short propagation delays: Depending on the power supply, the propagation delays are usually around 25 nS to 50 nS. 3. Rise and fall times are controlled: The rise and falls are usually ramps instead of step functions, and they are 20 - 40% longer than the propagation delays. 4. Noise immunity approaches 50% or 45% of the full logic swing. 5. Logic levels in a CMOS system will be essentially equal to the power supplies since the input impedance is so high.Characteristics of TTL logic: 1. Power dissipation is usually 10 mW per gate. 2. Propagation delays are 10 nS when driving a 15 pF/400 ohm load. 3. Logic levels vary from 0 to 5 voltsSolution: Characteristics of CMOS logic: 1.

What is the advantages of domino logic?
less dynamic power
What is the relation between power and distance?
Power is inversely proportional to distance. As distance from a power source increases, power dissipates or decreases. This relationship is described by the inverse square law, which states that the intensity of power decreases by the square of the distance.
