The basic difference between the two is that frequency is defined as the rate of radio signal to send and receive communication signals, whereas bandwidth is defined as the difference between the highest and the lowest frequencies of a signal generated .
Read moreHow do you calculate bandwidth of low-pass filter?
If you consider an ideal low-pass filter with cut-off frequency of fc, all frequencies greater than fc will be removed. Then it’s bandwidth is equal to fcHz (from 0 up to fc) . The total bandwidth BT is simply twice that: BT=2fc, since we are also considering negative frequencies, from −fc up to fc.
Read moreHow is bandwidth related to Risetime?
Historically, oscilloscope frequency response tended to approximately follow the rule: Bandwidth x risetime = 0.35 . This corresponds to a 1- or 2-pole filter roll-off in the frequency domain. Today, at the high end, most real-time digital oscilloscopes more closely follow this rule: Bandwidth x rise time = 0.45.
Read moreWhat is the relation between rise time and maximum allowable channel bandwidth?
We saw that the rise time of a signal is inversely proportional to its bandwidth and that the product of these two parameters is always approximately 0.35.10 Eki 2019
Read moreWhat is rise time?
Rise time is the time taken for a signal to cross a specified lower voltage threshold followed by a specified upper voltage threshold . This is an important parameter in both digital and analog systems. In digital systems it describes how long a signal spends in the intermediate state between two valid logic levels.

For applications in control theory, according to Levine (1996, p. 158), rise time is defined as “the time required for the response to rise from x% to y% of its final value”, with 0% to 100% rise time common for underdamped second order systems, 5% to 95% for critically damped and 10% to 90% for overdamped ones .
