Applications of wien bridge oscillator?
A Wein Bridge Oscillator is a oscillator which is used for the measurement of Audio Frequency.
Why coaxial cable not used in low frequency?
Coax is normally used in high frequency applications due to its ability to shield the signal. The coax construction prevents radiation, while at the same time prevents noise pick up. It is the shielding that makes coax a better choice at higher frequency, however coax can be used as low as audio frequencies. Lower frequency systems do not need the shielding due to the long rise times. They are not as sensitive to noise pick up and generally do not radiate.
Why you use 455kHz frequency as an intermediate frequency in communication?
The intermediate frequency in the superheterodyne receiver is chosen as the desired compromise between sensitivity and selectivity. 455kHz is used in AM broadcast applications, while 10.7mHz is used for FM. The IF stage is tuned for a steep skirt passband at that frequency, allowing only the desired heterodyned (shifted) input signal to make it through to the demodulator.

What are the characteristics and applications of high frequency signals?
High frequency signals have a short wavelength and high energy. They are used in applications such as telecommunications, radar systems, and medical imaging. These signals can carry large amounts of data quickly and are also used in wireless communication technologies like Wi-Fi and cellular networks.
What are the characteristics and applications of high frequency waves?
High frequency waves have short wavelengths and high energy. They are used in various applications such as telecommunications, radar systems, medical imaging, and industrial processes. These waves can penetrate materials and provide detailed information for imaging and communication purposes.
The frequency range 30MHz - 300MHz is?
The frequency range 30MHz - 300MHz is part of the VHF (Very High Frequency) spectrum. It is commonly used for applications such as FM radio broadcasting, air traffic control, and television broadcasting. It falls between the HF (High Frequency) and UHF (Ultra High Frequency) ranges.

What is correct term when describing frequency range of 3 kHz to 300 GHz?
The frequency range of 3 kHz to 300 GHz is referred to as "radio frequency" (RF) spectrum. This range encompasses various types of electromagnetic waves used in communications, broadcasting, and radar applications. It includes subcategories like Very Low Frequency (VLF), Low Frequency (LF), Medium Frequency (MF), High Frequency (HF), Very High Frequency (VHF), Ultra High Frequency (UHF), Super High Frequency (SHF), and Extremely High Frequency (EHF).
What does Sending out a pulse of high frequency radio waves?
Sending out a pulse of high frequency radio waves involves transmitting electromagnetic radiation at a fast rate. This can be used for applications such as communication, radar systems, and medical imaging. The high frequency allows for fast transmission and reception of data or information.
Why can't a conventional pn junction be used for high frequency switching applications?
If the reverse recovery time of the diode is too long for the operating frequency, the diode will never turn off.
High frequency induction heating?
High frequency induction heating is a process that uses an alternating magnetic field to generate heat in a conductive material. This method is commonly used for applications such as hardening, tempering, and brazing of metals. The high frequency of the electromagnetic waves allows for rapid and efficient heating of the material.
