• Oscillator Settings: Oscillators generate signals at specific frequencies, and their settings determine the output frequency of the circuit.
• Modulation Unit: Modulation techniques, such as amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM), can alter the frequency content of signals.

Ranges and Their Impact on Circuits

Different frequency ranges affect electronic circuits in various ways:

• Low Frequencies (1 kHz - 3 MHz): These frequencies are susceptible to interference from power line noise and can induce unwanted signals in sensitive circuits.
• Medium Frequencies (3 MHz - 30 MHz): AM radio frequencies can cause interference in nearby electronic devices, especially if they lack adequate shielding.
• High Frequencies (30 MHz - 300 MHz): VHF frequencies are used in many consumer electronic devices and can be affected by external interference sources such as nearby transmitters.
• Very High Frequencies (300 MHz - 3 GHz): The proliferation of wireless communication technologies operating in this range can lead to crowded frequency bands and potential interference issues.
• Ultra High Frequencies (3 GHz - 30 GHz): Microwave frequencies are highly directional and require line-of-sight communication, making them less prone to interference but vulnerable to obstacles in the transmission path.
• Super High Frequencies (30 GHz - 300 GHz): Millimeter-wave frequencies offer high data transfer rates but are easily attenuated by atmospheric conditions and physical barriers.

Vulnerable Electronic Components

Certain electronic components, modules, and devices are more vulnerable to electromagnetic interference at specific frequency ranges:

• Semiconductor Devices: Integrated circuits, transistors, and diodes are sensitive to high-frequency noise and can malfunction in the presence of electromagnetic interference.
• Communication Modules: Wireless communication modules, such as Wi-Fi, Bluetooth, and cellular modems, operate in frequency bands that are susceptible to interference from other nearby wireless devices.
• Sensitive Sensors: Sensors used in medical equipment, scientific instruments, and automotive systems may experience inaccuracies or false readings when exposed to electromagnetic interference.
• Control Systems: Electronic control systems in industrial machinery, automotive vehicles, and aerospace applications rely on precise signal processing and can be disrupted by electromagnetic interference.
