Your assignment is to prepare and submit a paper on investigation of a turner circuit. A wider frequency bandwidth has its application in more complicated transmissions like DAB used in digital radio, PAL/NTSC used in TV, and DVB-S/DVB-T/DVB-C used in digital TV. Several subcarriers within the receiver are used to transmit the frequency bandwidths as intermediate frequencies (IF). The subcarriers’ processing occurs, or the full bandwidth underwent sampling with A/D at a faster rate than the Nyquist rate. The expected rate is at least twice the IF frequency (Vendelin, Pavio, and Rohde, 2005).  .The most straightforward tuner from a circuit connection of a capacitor and an inductor is the radioactive crystal. The inductor or the capacitor is made to be variable to create a resonant circuit that responds at a particular frequency to an alternating current.  .The addition of the demodulator to a tuner as a detector results in producing the smallest unit of the radio receiver called the crystal. Practically, radio receivers use a superheterodyne receiver, while the older models would use ganged variable capacitors that are mechanically operated to realize manual tuning. Often there were several provisions for sections on a tuning capacitor to allow for switching between different frequency bands or to tune various stages of the receiver in tandem. A tuner can also be a radio receiver or any standalone audio component forming part of a sound system connected to a separate amplifier (Serway and Vuille, 2007). Tuning as a verb would be used in a radio context to mean adjusting the radio receiver to receive the desired radio signal carrier frequency that is being utilized by a particular radio station.
.The experiment made fair use of a function generator and oscilloscope. I used resistors (1k, 3k, 470Ω), capacitor (22pF, 6.8nF), inductor (47mH), BC108 transistor, and a D.C. power supply (10v). After the identification of the components used, the next step involved stating their properties. A column-shaped breadboard was used to connect the function generator to the circuit’s input with the signal of entry set to 100mV peak-to-peak and 5 kHz. The ground terminal of the function generator had a looping with a 1k resistor and 470 Ω resistor. Feeding of the signal generator from the function generator occurred at the base of a BC108 transistor through a voltage divider consisting of 3.9 k and 1k resistors. A capacitor (6.8 nF) first received the signal from the function generator before the voltage division process (Progri, 2011).
