Does keying on a sine wave at a zero-crossing reduce its bandwidth?

Does keying on a sine wave at a zero-crossing reduce its bandwidth?
  1. What is bandwidth in sine wave?
  2. What is bandwidth of signal that can be decomposed into 5 sine waves with frequencies 0 20 50100 & 200 Hz all peak amplitudes are same draw the bandwidth?
  3. How do you find the bandwidth of a sine wave?
  4. Which signal has a wider bandwidth a sine wave with a frequency of 100hz?

What is bandwidth in sine wave?

A sine wave does not have a bandwidth. The bandwidth is zero because it's a single frequency.

What is bandwidth of signal that can be decomposed into 5 sine waves with frequencies 0 20 50100 & 200 Hz all peak amplitudes are same draw the bandwidth?

Answer: The band width of the signal is 200Hz. Explanation: Given five sine waves with frequencies 0, 20, 50, 100, and 200 Hz.

How do you find the bandwidth of a sine wave?

Bandwidth is the range of frequencies from lowest to highest. For a sinewave, lowest equals highest, so bandwidth is zero.

Which signal has a wider bandwidth a sine wave with a frequency of 100hz?

Which signal has a wider bandwidth, a sine wave with a frequency of 100 Hz or a sine wave with a frequency of 200 Hz? Each signal is a simple signal in this case. The bandwidth of a simple signal is zero. So the bandwidth of both signals are the same.
