What else can I help you with?
When low frequency signals added to high frequency signal then the envelope signal will follow which signal?
the low frequency signal which is nothing but the message signalNeither. The envelope will be that of the difference beat frequency. To get the envelope to follow the low frequency input signal you need to mix (multiply) the two signals, not add them.
Is The carrier frequency is usually lower than the modulating frequency?
when the frequency is low , energy will be obviously low. To increase the energy of the signal we need to increase the frequency. This is achieved by multiplying the message signal with the carrier signal (with high frequency).
What happens if we sample the signal at sampling frequency nearer to signal frequency?
If you sample at more than the Nyquist frequency (one half the signal frequency) you introduce an aliasing distortion, seen as sub harmonics.
Is step signal is a DC signal?
A: while a step can be of both polarity but it is a level change and it is DC LEVELS
What is signal modulation?
modulating signal is the message to be carried by the carrier signal.
Is DC signal is periodic?
Yes DC is periodic with zero frequency........and undefined fundamental time period To........
Why do highpass filters block the DC signal?
Because DC is the lowest frequency (0 Hz) so that it does not pass the filter.
What is the significance of zero frequency in the context of signal processing?
In signal processing, zero frequency represents the direct current (DC) component of a signal. It is significant because it indicates the average value of the signal and helps in analyzing the overall behavior and characteristics of the signal.
Why the frequency of a digital signal is infinite?
actually the frequency of a digital signal in infinite because assuming the signal is a square wave for each point in time eg 1 sec the amplitude can remain at max or "dc" for any number of bits assuming 1 bit = dc for 1 sec/clock cycle
How does frequency affect amplitude?
Frequency does not directly affect amplitude. Amplitude refers to the maximum displacement of a wave from its rest position, while frequency is the number of complete wave cycles that occur in a unit of time. However, in some systems like resonant systems, changes in frequency can affect the amplitude of the wave response.
How to removed a dc offset from the output of a frequency generator connected to a test circuit?
Run the test signal through a small isolation transformer.
What is the reason for high frequency in dc motor?
High frequency in a DC motor can be caused by factors such as mechanical resonance, electrical noise, or incorrect control signal frequency. These can lead to instability and performance issues in the motor operation. It is important to identify and address the root cause to ensure smooth and efficient motor performance.
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)
Comparison of amplitude modulation and frequency modulation?
Amplitude of the (high frequency) Carrier signal is varied with respect to low frequency of message signal is called amplitude modulation. Frequency of the carrier signal is varied with respect to low frequency of message signal is called frequency modulation.
When low frequency signals added to high frequency signal then the envelope signal will follow which signal?
the low frequency signal which is nothing but the message signalNeither. The envelope will be that of the difference beat frequency. To get the envelope to follow the low frequency input signal you need to mix (multiply) the two signals, not add them.
What signal has wider bandwidth sine wave with frequency 100HZor 200HZ?
The signal with a frequency of 200Hz has a wider bandwidth compared to a signal with a frequency of 100Hz. Bandwidth is determined by the range of frequencies present in a signal, so a higher-frequency signal will have more frequency components and thus a wider bandwidth.
What is the frequency of 27 DC volts?
Basically, "frequency" applies to AC, not to DC. If you want to assign it a frequency, the frequency is zero. The amount of volts is not relevant.
