Final answer:
A 1080p HDTV signal at 30 Hz will display images at 30 frames per second, offering high-definition content. UHF TV channels operate in a frequency range between 470 and 1000 MHz, with video signals being AM and audio FM.
Step-by-step explanation:
A 1080p HDTV signal with a frame rate of 30 Hz will reproduce images at 30 frames per second (fps). This means that the TV displays 30 still pictures every second to create the illusion of moving images. Since 1080p is a high-definition format, it offers a resolution of 1920x1080 pixels, which results in very clear and detailed images for viewers. Television broadcasts, including ultra-high frequency (UHF) TV channels, typically operate in a frequency range between 470 and 1000 MHz, and they utilize different types of modulation: the TV video signal is Amplitude Modulated (AM), while the TV audio is Frequency Modulated (FM). These standards are for over-the-air transmission, which might differ when comparing to cable or satellite transmissions, which often occur at higher frequencies and are adopting high-definition formats more rapidly.
