In some versions of the circuit, a transis-tor type audio transformer (e.g., an LT44) is substituted for the resistive load in order to maximize signal transfer. However, even with this arrangement, the audio output is very low, and at least one additional stage of pre-amplification will be required ahead Further, because tuned circuit Q is raised,File Size: KB.   Handbook of Analog Circuit Design deals with general techniques involving certain circuitries and designs. The book discusses instrumentation and control circuits that are part of circuit designs. The text reviews the organization of electronics as structural (what it is), causal (what it does), and functional (what it is for).Pages:
