State advantages and disadvantages of amplitude modulation.

When the amplitude of carrier wave is varied in accordance with the modulating signal, the process is called amplitude modulation.

i. In amplitude modulation, carrier is varied in accordance with the message signal. ii. The higher the amplitude, the greater is magnitude of the signal. So even if due to any...

Advantages: For cells connected in parallel in a circuit, the circuit will not break open even if a cell gets damaged or open. Disadvantages: The voltage developed by the cells in parallel connection...

a1 = 1.5 a2 To find: \(\frac{I_1}{I-2}\) Formula: I ∝ a2 Calculation: From formula, \(\frac{I_1}{I_2}=(\frac{a_1}{a_2})^2=(\frac{1.5_{a_2}}{a_2})^2\) = (1.5)2 = 2.25

a1 = 2.5 a2 To find: \(\frac{I_1}{I-2}\) Formula: I ∝ a2 Calculation: From formula, \(\frac{I_1}{I_2}=(\frac{a_1}{a_2})^2=(\frac{2.5_{a2}}{a_2})\) = (2.5)2 = 6.25

Given: B0 = 510 nT = 510 × 10-9 T To find: Amplitude of electric field (E0) Formula: E0 = B0C Calculation: From formula, E0 = 510 × 10-9 × 3 × 108 = 153V/m

Some one please give this answer

Advantage of GM Crops: 1. Genetic modification has made crops more tolerant to abiotic stresses (cold, drought, heat, salt) 2. Viral resistance can be introduced. 3. Over ripening losses can be reduced eg: Flavr...
