Root Mean Square and Peak Sine Generator with FPAA

In studio analog transmission systems, when testing amplifiers, it may be necessary and convenient to have a device that can generate the root mean square (RMS) and peak values (Up) of the test signal quasi simultaneously. This possibility greatly helps to establish the transmission properties without irreversible damage. In another approach, it also supports in a way the determination of musical performance, since the “peak” and the effective signal level can be understood as a practical signal. In this paper, a device is presented that can produce this signal in a tunable manner using a programmable analog array (FPAA) and a microcontroller using a special hybrid circuit [1] [2]. It is described as a new application of the hyrid cell proposed in our previous articles.
