Input Supply: 230 VAC/50Hz mains operated. Dimension: 27cms x 17cms x 10cms. Weight: 500gms
Objectives:To construct T or section high pass filter and to study the frequency response that passes only high frequencies. That is, R will cut off low frequencies.
Input Supply: 230 VAC/50Hz mains operated.Dimension: 27cms x 17cms x 10cms.Weight: 500gms
Objective:To construct passive band pass filter and observe the frequencies that pass in between low and high frequencies. To note down lower cut-off frequency and upper cut-off frequency.
Objectives : To construct T or section m derived low pass filter and observe the frequency response. It should be however noted that to divide the impedance of a capacitor by m, its capacity must be multiplied by m. To observe the cut off frequency and to plot the graph between frequency and attenuation.
Objectives: To construct Equaliser and test the frequency response of the network.

Objective: To construct T-attenuator 1dB -9dB. Audio frequency input (Vi) should be given from audio frequency oscillator. The output of the T-attenuator Vout is taken at the output. Attenuation (dB) =-20 log (V0/Vi) is measured.
Objectives : To construct attenuator and calculate the attenuation 0.1db, 0.2dB and 0.3dB. Audio input sine wave Vi should be given from audio frequency oscillator. The output of the attenuator should be observed. Attenuation (dB) = -20 log (V0 / Vi).
Objectives : To construct T and type high pass filter and observe the output frequency response.
Objectives : To construct composite section HPF and observe the output frequency response that passes only high frequencies.
Objectives : To construct composite Band Pass filter and to study that the BPF passes in between low and high frequencies and observe the lower cut off frequency and upper cut off frequency.
