Freeze In digital picture manipulators, the ability to stop or hold a frame of video so that the picture is frozen like a snapshot. The storing of a single frame of video. The number of cycles a wave completes in a given time interval. A common process to vary the frequency of a carrier signal in proportion to a signal of interest. The range of frequencies from the lowest to the highest that a particular electronic circuit is capable of handling without distortion.
Most circuits have limits to the range of frequencies that they can handle.
Frequency response is measured in cycles per second or Hz. The human ear has a frequency response of about 20 to 20,0000 Hz because it can hear and distinguish sounds within this range. In audio systems, a frequency response matching this performance of the ear would be considered high-fidelity. For security systems, audio frequency responses of 50 to 12,000 Hz should be considered sufficient. The time spent at the blanking level prior to the horizontal sync pulse in a video waveform.
