Does proteus vulgaris produce h2s?
Yes, it does. It is Indole Production positive, H2S positive, and Motility positive. This can all be seen using SIM agar. Yes, it does. It is Indole Production positive, H2S positive, and Motility positive. This can all be seen using SIM agar.
Is sporosarcina gram positive?
Yes, Sprosarcina is gram positive. It also has flagella (halophilia)
Do metal ions have a positive charge?
On their own metals have no charge. Metal ions have a positive charge.
Is east positive or negative?
You can assign positive numbers to east and negative to west - or you can do it the other way round. Which direction you call positive is really quite arbitrary. In Google Maps for example, east appears as positive.
Particles with a positive charge?
Protons is a particles with a positive charge.
What is positive and negative modulation?
in order to transmit the video signal amplitude modulation is used. the composite video signal has distinct polarity of black and white levels in the picture.1.positive modulation :- in this type of modulation, increase of brightness toward white causes increase in carrier amplitude peak white has 100% modulation while black and sync level have lower and minimum modulation respectively2.negative modulation :-in this type of modulation,the sync tip level are at 100%.blanking level correspond to black is at 75%and increase in brightness toward white causes decrease in carrier amplitudeNegative modulation is preferred over positive modulation because impulse interference is difficult to deal with and random increase in signal is similar to existing sync pulse.these interference result in generation of black spot and white blobs.
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
Need for modulation?
modulation
What are the two types of angle modulation?
Frequency Modulation and Phase Modulation
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
How velocity modulation and density modulation related to each other?
due to velocity modulation density modulation occurs in TWT
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
Why frequency modulation and phase modulation are called angle modulation?
i dont know ans. of this.
How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.
What is the unit for modulation index?
Modulation index is also called as Modulation depth. The modulation index of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level.
