Block diagram. The NE612 is an integrated circuit for processing of signals, such as in the transmission of radio signals. It consists of a oscillator and a mixer. [1] It can handle signal frequencies of up to 500 MHz and local oscillator frequencies of up to 200 MHz.
In the Armstrong method, the audio signal and the radio frequency carrier signal are applied to the balanced modulator to generate a double sideband suppressed carrier signal. The phase of this output signal is then shifted 90 degrees with respect to the original carrier. The balanced modulator output can either lead or lag the carrier's phase.
As a mixer, its balanced operation cancels out many unwanted mixing products, resulting in a "cleaner" output. It is a generalized case of an early circuit first used by Howard Jones in 1963, [ 2 ] invented independently and greatly augmented by Barrie Gilbert in 1967. [ 3 ]
Instead, they record the date or time that the page was most recently edited or purged.

For example, if 50 MHz is mixed with 94 MHz to produce an output on 144 MHz, the third harmonic of the 50 MHz may appear in the output. This problem is similar to the Image response problem which exists in receivers. One method of reducing the potential for this transmitter defect is the use of balanced and double balanced mixers.

A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .
