How is it possible to represent a complex exponential signal with a frequency of 20Hz using a sampling frequency of 30Hz?
A 20Hz signal must be sampled at a minimum of 40Hz to have a chance of sampling both peaks and to get a reasonable representation it must be sampled at a minimum of 100Hz.For a sampling rate of 30Hz the Nyquist frequency is 15Hz and since 20Hz is above that it will generate the alias signal of 10Hz in the sampled data instead of the original signal of 20Hz. Therefore it is not possible to do what you ask.
What is the lowest frequency that can be generated using mode 1 if the crystal frequency is 11.0592 MHz Show your calculations?
To calculate the lowest frequency that can be generated using mode 1, we need to divide the crystal frequency by two. So, the lowest frequency that can be generated in this case would be 11.0592 MHz divided by 2, which is equal to 5.5296 MHz.
What is the purpose of a local oscillator in mixer?
A local oscillator is a device that generates a sinusoidal signal with a frequency such that the receiver is able to generate the correct resulting frequency, or intermediate frequency (IF), for further amplification and conversion into audio detection. There is one local oscillator in a single conversion super heterodyne receiver where heterodyning or mixing is used to generate beat frequencies, which may be the sum or the difference of two frequencies. The local oscillator is usually adjustable and in step with the increment or decrement in the receiver frequency. For instance, if the receiver is tuned to 1,455 kilohertz (kHz) as radio frequency input (RF-in), the local oscillator frequency (LOF) may be set to 1,910 kHz for a so-called high side injection. The two signals are fed to an electronic device known as the mixer, which derives LOF - RF-in = IF or 455 kHz, which suggests why amplitude modulation (AM) broadcast receivers have about four stages of low-power amplifiers tuneable to 455 kHz.

What was the effect on the input impedance of lowering the operating frequency?
The input impedance should increase slightly for the lower frequency, when using a capacitive circuit.
Is it possible to make an Electronic Pest Repellent using Arduino and make ultrasound from 30 kHz to 200 kHz frequency?
Yes you can!Just generate a rectangle signal with a frequency bigger than 20kHz and amplify it by power transistors.
Which is the least sustainable practice?

What system reserves channel 16 for distress calls?
channel 16 I am a former USCG Radioman. Make sure you are using a marine band radio otherwise the channels do not line up. The frequency you need is 156.800Mhz. Also the you use that for calling also. Then the USCG if it is not a distress call will switch you to a working frequency that is usually ch 22 or 157.100Mhz. Also for hf the frequency is 2182Khz. Used to use 500Khz for Morse code but it is not monitored anymore. This was a real problem when I was stationed in Portland ME as they Canadian Fishing fleet used 22 as its working frequency so they were always stepping on us when we were working on 22.
What is function of an oscillator?
A local oscillator is an electronic device used to generate a signal normally for the purpose of converting a signal of interest to a different frequency using a mixer. This process of frequency conversion, also referred to as heterodyning, produces the sum and difference frequencies of the frequency of the local oscillator and frequency of the input signal of interest. These are the beat frequencies. Normally the beat frequency is associated with the lower sideband, the difference between the two.
How can you determine the frequency at which you are vibrating?
You can determine the frequency at which you are vibrating by using a tool called a frequency counter or by analyzing the vibrations using a device like a smartphone app that measures frequency.

How to find the frequency of a wave using its wavelength?
To find the frequency of a wave using its wavelength, you can use the formula: frequency speed of the wave / wavelength. The speed of the wave is a constant value, so you can divide the speed by the wavelength to calculate the frequency.
How do you generate xslt using vbnet?
The best approach is to put the fixed content in an XML file, and transform it using XSLT to generate the dynamic content.
