The signal m(t), whose frequency spectrum M(f ) is to be transmitted from one station to another. Let the signal be nor- malized, i.e., -1 ≤ m(t) ≤ 1. Find the bandwidth of the modulated signal:
(a) If USSB (upper single sideband) is employed.
(b) If DSB (double sideband) is employed.
(c) If an AM modulation scheme with a modulation index of 0.8 is used.
(d) If an FM signal with the frequency deviation constant k = 60 kHz is used.
Q. Explain Current and Magnetic Force? The rate ofmovement of net positive charge per unit of time through a cross section of a conductor is known as current, i(t) = dq / dt
How to design an Oscillator Circuit (500 MHz range) with no Op amps?
Input Output Operations Many times microprocessor has to accept data from input port and send data to output port to interact with the real world. Input port is tri st
A 3-phase transmission line is 200km long. The line has a per phase series impedance of 0.25+j0.45 Ω/km and shunt admittance of j7.2 μS/km. The line delivers 250MVA, at 0.6 lagging
