Well you can say that the frequency of DC is constant or not?
Yes it is constant at Zero Frequency. No, DC or Direct Current only means that the current only goes one direction, but it can have a frequency. You can have a square wave, sawtooth wave or sine wave that never goes from positive to negative or negative to positive and it would be a direct current with a frequency.
What is the voltage wave form?
It is positive and negative signal in the frequency of wave form, the voltage of amplitude modulation, that carriers the signal of frequency.In the process of graph showing result ...
Why does the output frequency of a full wave rectifier double that of input frequency?
One cycle of the AC input consists of a positive half-cycle followed be a negative half cycle. The FW rectifier basically reverses the polarity of one of the half-cycles, so there are now two positive pulses per single input cycle, effectively doubling the frequency. Of course the rectifier may be wired for the opposite polarity, with two negative pulses per input cycle, but the same principle applies.
What measurement can vary with AC current by not DC current?
HZ. Hertz is the name given to the frequency of the alternating circuit. Direct current (DC) has no frequency since one wire is always positive and the other is always negative; but AC (Alternating Current) rapidly changes polarity, and does so at a rate that is defined by HZ.
How do you convert cellphone gsm frequency to another gsm frequency?
How do you convert cellphone gsm frequency to another gsm frequency?"
Can frequency of wave be negative?
No, frequency of a wave cannot be negative. Frequency is defined as the number of complete cycles of a wave that occur in a given time period, and it is always a positive value.
Are there negative dimensions?
No, but dimensions can be to negative powers. For example, the dimension for frequency is [T-1].

Is punishment a reinforcer?
Punishment is not a reinforcer. there is Negative Punishment and Positive Punishment, and also Negative Reinforcement and Positive Reinforcement.*Negative Punishment is a consequence withdrawn following a response that causes a behavior to occur with less frequency.*Negative Reinforcement is a consequence withdrawn following a response that causes a behavior to occur with greater frequency.*Positive Punishment is a consequence delivered following a response that causes a behavior to occur with less frequency.*Positive Reinforcement is a consequence delivered following a response that causes a behavior to occur with greater frequency.
What is frequency of dc?
You can say DC voltage has a frequency of zero Hz.Because it is unidirectional in nature (may be positive or negative)
Does both positive and negative reinforcement increase the frequency of responses?
Yes, both do. Negative reinforcement is quicker but positive reinforcement is more permanent.
What is the physical significance of negative frequency?
just ony in analysis purpose its not practically possible
If input frequency of a full wave rectifier be n then uotput frequency would be?
The output frequency of a full wave rectifier will be twice the input frequency. This is because full wave rectifiers process both the positive and negative cycles of the input signal, effectively doubling the frequency in the output waveform.
How do you make a frequency table of all negative numbers?
by counting the amount of numbers and puting them in a tally.
When the frequency in Hertz and the reactance positive or negative in Ohms are known can you determine component values such as inductance or capacitance?
Positive
In negative frequency-dependent selection such as in the study done on the water boatman insect the incidence of predation leads to an?
Increase in a rare genotype.
Is never a part of of a verb phrase?
"Never" is often used in sentences to indicate a negative frequency adverb that modifies the verb in the verb phrase. It does not directly form part of the verb phrase itself.
