The fundamental difference between zero and peak signals is generally that? A. zeros are much more clearly defined than the peaks.
B. peaks are more clearly defined as nulls.
It rotates 360 degrees antenna produces more peaks zeros.
D. rotated 360 degrees antenna produces more zeros than the peaks
Please someone help me, please
I think you do not have any issue there. From the responses, I guess this is about peaks and nulls in a directional antenna.
In almost all cases, the zeros at the reception of a directional antenna are-much-more clearly defined than peaks. Peaks tend to be large lobes, with the zeros of very narrow and well defined between the vertices.
For example, a dipole antenna has a sensitivity model that resembles a donut with the wire leading through the hole in the donut. When the ends of the antenna are made straight to the source, there is a very strong null.
An antenna has a model home, which also looks like a donut, in this case the shape of the ring is aligned with the sinuous curves. So take an AM radio and point the ferrite core to a radio station and you will find a strong null at the reception.
Other types of directional antennas also draws strong peaks with relatively blobby looking. Perform a search for radiation pattern "and look at pictures.
B.peaks are more clearly defined as null values.
