a. Determine how color sync burst and H deflection sync vary in amplitude and frequency. Also explain the difference in timing among the 3.58 MHz color sync burst and 3.58 MHz chrominance signal.
b. Why is the chrominance signal transmitted with the subcarrier suppressed?
Q. Regions of operation in BJT ? Transistor find many applications like amplifier, switch etc. depending upon the polarity and the magnitude of the applied voltages across the
Vee vcc
Why is the signal first attenuated and then amplified?
1) Assume that we are given the continuous-time signal xa (t) = xa1 (t) + xa2 (t) + xa3 (t), where, xa1 (t) = 2 + cos3 (2pf1 t + p 3 ) + 2 cos(2pf2 t), xa2 (t) = 2 cos(2pf3 t)
conclusion about electrical engireng??
Explain the different types of polarizations. Polarizations are of three types. i. Electric polarization ii. Ionic polarization. iii. Dipolar polarization.
Circuits, which provide sinusoidal waveforms, are but useful in themselves and form the basis of many other circuits, such as square and triangular waveform generators, and clocks.
