Question

A signal has a bandwidth of 40 hz and its highest frequency is 100hz, what is its lowest frequency

Answer 1

Answer:

Explanation:

Although the signal can have the same bandwidth (1000 Hz), the range does not overlap. The medium can only pass the frequencies between 3000 and 4000 Hz; the signal is totally lost. 64. Example 11 We have a channel with a 1 MHz bandwidth.

Answer 2

Given: Bandwidth= 40Hz, highest frequency = 100Hz

To find: lowest frequency

Solution: we can find the Bandwidth with the difference between the upper frequency and the lower frequencies in a continuous frequency band and its unit is hertz/ cycles per second

let the bandwidth be B, highest frequency be Hf, lowest frequency be Fl

So, B = Hf - Hl

40 = 100 - Hl

Hl = 60 Hz

Therefore, the lowest frequency of the signal will be 60Hz.
